A friend has been talking about starting a D&D group ever since BG3 dropped and I already have a matching character concept complete with partial backstory. However, between the OGL fiasco and the dubious plans WotC have for D&D 6e I really don't feel like buying the required book or pushing my friend to get his campaign worked out.
If you like a little more crunch, Pathfinder or Starfinder.
If you like a little less crunch, Cities without Number/Stars Without Number/Worlds without number.
If you want something different, Vampire: The Masquerade.
If you want something completely different and to only last a session, 10 Candles.
Pathfinder 2e is really good. Its a little more complex than 5e but you have a lot more character variety in terms of crunch which then spills over into more interesting roleplay. Its also pretty hard to make a useless character unless you just straight up try to on purpose.
My very favorite system is Apocalypse World; it always plays out as high-drama operatic pulp. It does tend to go PvP in later sessions, so it's definitely not for every group.
I also enjoy Blades in the Dark, a heist game set in a haunted Victorian London-inspired city. There are a lot of great innovations that mean the players don't have to meticulously plan out their session (often wasting time on contingencies that are irrelevant), and instead can jump right in and get to the juicy bits.
Mothership is a great sci-fi horror OSR (old school revival) game that is very modular and has a ton of pre-written modules. Normally I prefer a more improvised style, but this is a solid ruleset that works well towards building the tension required for the genre.
If you're just looking for a one-shot, Fiasco is always a great time: very rules light and more like a writers room exercise than most RPGs, but there's no better game for hilarious hijinks inspired by films like Fargo or Burn After Reading.
Dogs in the Vineyard is another great one by the same designers as Apocalypse World in which the players are teenage paladin gunslingers in a weird old west populated by demons and heretics. The players come to town with absolute moral authority and may judge whomever they wish, but there's no guarantee they're really the good guys even though their characters absolutely see themselves that way.
DnD somehow tries to sell itself as a combat simulator. And yeah, it's combat system is more fleshed out than many other roleplaying systems, but at the end of the day a lot of the combat interactions are down to the DM to decide so it ends up being a normal roleplaying game with the occasional stumble into a waste-deep muck or rule interactions for what ended up being almost no reason.
I love the idea of DnD, but every group I've ever played with just made it such a drag. I've never had fun actually playing it. So now I follow the memes and that's about it.
I enjoy the imagination and storytelling most of all. Coming up with an adventure for all of us to discuss and enjoy is fun!
But most of the groups I've played with take forever to do anything. We'll spend like 4 sessions just trying to wrap up a scenario in a tavern and move on. I need to find a DM who can keep the action going and not just give people all the time they want to talk their way through a situation before acting. And I also need to find players who are more decisive.
I've played with five completely different groups in the past 20 years, and all of them were exactly like this.
20ish years of never saying no, and not once was it worth the time and effort. no matter the group or system, it's always three hours sitting on an uncomfortable chair waiting for people to stop cutting up, playing handheld games, scrolling their phone, throwing all their skills at a random piece of scenery, or whatever it is they're doing to waste literally everyone's time instead of actually engaging with the game in a good faith attempt to have fun in a group, so that I can verify that I'm going to do the expected and obvious thing to do before waiting twenty minutes to do it again because now everyone has to be filled in on what JUST FUCKING HAPPENED because none of them were actually paying any fucking attention to anything but their next stupid fucking joke. it's like a high school group project with random partners except they're all useless drunk on top of everything else. if good games are that rare then why would anyone bother in the first place? fuck tttrpgs with a rusty rake.
