Mac and cheese? ...can I eat you? I'm obsessed with it, got my brother hooked too. <3 Welcome to PC, MacNCheese! I'm actually on Steam too, though I don't have very many games. Mostly into Terraria right now!
If you're a spriter, I'd recommend dropping by the Pixel Art section, as it's of course the best place for all your spriting needs. Members also open up their own pixel art shops there over at the Pixel Projects subforum, so if you're ever looking to have some art done for you, that'd be your best bet. :D And PC is actually pretty well known for its ROM hacks (you may already know that though haha). We've got tools, tutorials, and other resources for you to use over at the Emulation section, so hopefully that helps you out in making your game~ maybe one day you'll even be the one to tutor members new to hacking. :3
So yeah, have fun here and I'll see you around! You can always contact me if you're confused about anything here, too. Enjoy your stay! :D
