What are your favorite ComputerCraft games/what makes a good one?

I've been running out of ideas for things to make. So much so that I've ended remaking Sketch (which is very close to beta testing by the way). I'll never finish something I feel is useless or will never be used, like an email or chat program (honestly, I've thought about it tons). So I thought I might look at making a game and game engine.

So basically my question is, what types of games do you want to see and/or what are your favorite games for ComputerCraft? This engine would probably resemble Bedrock a bit, but I'm not sure if I'd bother releasing it really given how little people seem to bother with other APIs.

So yea, I might find it deathly boring and stop, but it'll be interesting to see what you think.

I would really enjoy a game like Bitcoin Billionaire or Virtual Beggar. That sort of thing would be cool; plus the style would fit it I think.

An easy to use, beginner-friendly engine should do it. You may want to look at App Inventor from MIT (its the thing we use in my class) and it has tons of possibilities. It works with blocks which you attach to easy other like Lego to make the code. I would love to see such a thing but remember you also need to be able to let the user add stuff like sounds or animations (even though with these pixels animations are really hard). If you do play a bit around with App Inventor you will see what I mean.
