I dunno, I like the way this one is set up. You have 50 battle points, each field battle takes 5 points, you regenerate 1 point every 3 minutes. To get more cards you hunt, which is a point-push fps sort of setup. Hunting uses tickets, which you get 1 free per day and mobs drop them, along with colisseum passes, which are used for the pvp fights (which are also generated, you're not making choices against them in real time or anything.) It's paced well enough for me that I can get on it for 30 mins - 1hr a day, then leave it alone for another day without having to spend real money on anything. I don't need another 3hr time crunch on my hands atm.
