Random thoughts on a card-based fighting game: I was looking at this game on BGG called Pulsar. I'm interested in trying it because it looks pretty fun. Anyways, if you look at the picture of the space cards laid out in a grid, something similar could be used to define the borders of an arena/fighting area. Players start head to head in the middle and take turns playing cards from their hand that attack/defend/move-attack or something like that. Slapshots system is pretty interesting and could be used in a way with a certain number of attack trumping another number, but a defense card beating an attack unless a higher defense card is played (like the goalie cards)! I actually really like this idea! MAYBE it could even be looked at as a trick-taking game/fighting game in that there could be exchanges of combos that whoever comes out on top deals the hitpoint damage. I had actually brought a pack of index cards for us all to brainstorm at Enrons bachelor con but we were pretty much packed end-to-end with games to play, never bothered to bring it out.
Edit: So say we're working with a 5 x 5 grid, maybe it can be somewhat spherical shaped (or octagonal or whatevs) and certain attack cards can have movement properties that move the fight in one of the 4 cardinal directions. BUT, if you're already at the edge of the arena, and you only have a "move fight to the right" card, you'd have to use it's less effective lower damage "straight attack" stat. ALSO, if you're playing your cards on tops of the grid, maybe you have to turn over the arena cards where your fighters have currently moved and there could be different effects that change the rules for battle. Something like "crowd mobs/movement properties nullified this turn" or something like that.
Edit2: THEN, we can totally make a kickstarter for it and like totally get rich/pay for printing of the game :)
It's almost 3am, I'm bored at work, let a guy dream
EDIT3: Damn, Pulsar looks pretty sweet. Check out the pdf of the rules. It's got this fun looking movement mechanic with a d6 (vector die) where the result is the direction and speed you can move - pretty ingenious!
