Man, I love tabletop games with cards. Playing a caster in 5e was only fun for me if I had spell cards; having a list was confusing, and a list that included abilities was way too cluttered. Lasers and Feelings (and L&F hacks) has characters that fit on a business card. On one side.
#drawsteel 's character abilities are formatted so you just have cards. You have a character sheet with your stats and skills etc, but that's one (2-sided) page and a hand of cards that grow as you level.
Your options aren't a whole page of tiny scribbled if-thens on when you're allowed to do your cool thing. It's a hand of cards you can play if you have the Heroic Resource to spend, and then just pick back up.
It just takes all the complicated crunch of a full-fat TTRPG, and lets you grab your options with your mitts and see them laid before you. It's a great format for any character sheet.
