I'm pretty sure Doom will be the most popular (and my pick too), but I'll throw a shout-out to Epic Pinball; that Android table was the best one in the game anyway.
I didn't realize anybody else had ever played that game. I downloaded that from AOL back when I was signing up for a free month trial every month from those CDs in the mail.
There's a whole community around self-made games using the editor that came with it, including a website full of games and a forum. A few years back one of us published a book about the community (and how we all turned out trans).
I was so addicted to ZZT back then! The player-made worlds were such a delight, and my slow-ass computer which choked on so many then-current games ran them without trouble.
Jumping around with the pogo stick in Keen 6 was so much fun. I recently found the full game. Was surprised how hard that factory level was. But the music was still how I remembered it.
A couple of people have mentioned Raptor: Call of the shadows, which was an absolute favorite of mine. Skyforce Reloaded is pretty close in terms of gameplay. I wish there were more games out there like Raptor
Pretty sure I even bought the full game and never ended up getting very far. I also remember spending a little chunk of time on Hugo 3: Jungle of Doom, but could never figure it out enough to progress very far.
Edit: Another one I was trying to recall, the name was H.U.R.L.
I spent so many hours as a kid on my dad's Thinkpad playing Gravity Well. It came on one of those "50 Great Games" CDs or something like that. The goal is to claim all the planets in the system, which you do by simply landing on them, then building defenses against your opponents. It's so much fun because your ship has pretty realistic inertia and the planets have actual gravity wells. The AI opponents can be quite difficult and aggressive. Challenging and fun, with great sound effects for the time!
This screenshot is from an Internet Archive page for the game, but I'm pretty sure it's only the shareware version. I gotta check again when I get off work!
Edit: I'm 99% certain it's from this exact CD for anyone interested. I've never been able to find a full version unfortunately...
I forgot all about this game! My go-to strategy was to attack freighters from the other factions while they were in flight and force them to change sides. My space pirate empire was unstoppable!
Yes!! And you could kind of cheese the game by pressing both fire buttons in rapid succession (down arrow and 'd' I think). I loved making passes around an enemy's planet and staying just ahead of their defenses, and becoming basically an A-10 Warthog in space. It was kind of difficult since your bullets inherited your velocity so you had to shoot at weird angles 😁
I was a huge fan of Solar Winds: The Escape. Cool plot, aliens, dogfights, ship systems management, evil shadow governments, rebels.... what's not to love? It was my introduction to the genre and will always hold a special place
For real though, I'd love to see a modern take on this - something in between NMS, Mechwarrior, and FTL. I've not found anything out there with the correct combination of exploration, ship customization and management, and sinister plot. Several games get closer, but they're all missing something
I played a lot of TetriNET and Subspace Continuum with my old online community. Great times.
More detail edit:
TetriNET walked so Tetris 99 could run. Version 1 does not install on Windows anymore (but has a Linux version). Version 2 works, complete with its archaic user registration that asks for too many details.
Continuum is a large PvP arena Asteroids-like 2D space shooter. It's on Steam now. Starts tough to control and with a high skill ceiling, so be wary of the veterans. The Death Star Battle map is a blast with a big group. It feels like trying to speed through a narrow maze on bumper boats during a huge battle.
Colobot - don't think it was "shareware" but it absolutely came as a demo on ceebot.com (still hosted there today I believe). Literally THE game that got me into computer programming and whatnot.
Otherwise for actual shareware, I loved Jazz Jackrabbit 2, Crazy Gravity and The Worm (found it!)
I really wanted to play a couple shareware games called Jetpack Joyride, and Hot Chix n Gear Stix as a kid, but neither of them would play on my Windows XP netbook as they had a hard check for if you were on either Windows 95 or 98, even with compatibility mode.
Oh, would've been so frustrating! I remember having a Pentium 4 laptop with an NVIDIA GPU and that thing unsurprisingly cooked itself, so I then tried 1NSANE (Codemasters' soft body physics car game) on my crappy little netbook instead and it just couldn't handle it.
It would be some time before I was gifted an Acer Aspire with dedicated graphics and a busted screen that I could play 1NSANE again
Heretic was more than a Doom clone, it was developed using a modified Doom engine with the participation of Doom developers. It was a clever game in its own right, adding a lot of fresh elements to the then-budding FPS genre.
I was always struck by the similarity to the blue robot on that table to Cyborg from Rise of the Robots and I wonder if there was some cross-pollination there.
I played a lot of 2 games that nobody I've spoken to has ever heard of:
Mordor the depths of dejenol
Exile escape from the pit
Both were great, I think exile had been remade by the programmer with a different title too
There was a Mordor 2 shareware as well. The game never got a full release but laid the foundation for Demise: Rise of the Kutan (2000). The rights to the game were sold to Decklin and they released expansions Ascension (2016) and Revenge of the Tavern Keeper (2024). Demos for Demise and the expansions are available at https://www.decklinsdemise.com/
