I've been tinkering with my Steam Deck almost since I got it a month ago. I mostly use it hooked up to the TV with a PS5 controller. I have a problem with sticking to one game and tend to jump around a lot between them, but here are ones I can remember playing in the last week or so for a decent amount of time:
Fantasy Life i: Not usually a fan of cozy games - I like more direction - so this one looked right up my ally with an actual plot to follow along. I got about 10 hours in until the game started blocking my progress by requiring I find buddies to advance the story. I'm not interested in having to look up where they can be found, so I dropped it. It was a fun 10 hours, though!
Broforce: Bought it for the 3rd time on Steam so I could access player-made levels, something not available on other platforms. I love this game! Wish they'd make a sequel or even an official expansion.
Banjo-Kazooie and Tooie: I recently decided to test out 360 emulation on the Deck via Xenia and remembered these 2 were on it with better framerates and camera control than the originals. Pretty funny to use a 360 emulator to play N64 games, but until the fanmade PC ports are available it's the best way to play them.
My next tinker project is seeing if I can get the DS models and texture mod for Mario 64 EX working. I have a thing where I prefer to play official upgrades to graphics when possible, which is why I'm use the 3DS textures for Ocarina of Time on the PC port.
They don't have to. They can release the code and let people run their own servers once they're no longer interested in doing so. This costs them nothing.
Marvel Heroes Omega is one I recently discovered has private servers now. I really miss that one. The whole campaign is playable, but the server will be wiped once 1.0 of the emu comes out, possibly early next year.
