+2 despite writing a good amount of my own programs (mostly open source).
I just like making stuff on my own. New technologies are cool but I don't really care about them. It's not like I can afford them anyway. Even if they are FOSS it takes too much work to actually swap frameworks.
I found PEAK very fun in both multiplayer and singleplayer.
The best decision the devs have made is, I think, the fact that the map only resets every 24 hours. You get to keep trying the same map to master it, but also get something fresh every day.
I mostly played it in single player, and it's very satisfying to climb the mountain.
Is it Gex night?
