I haven't been buying any RIGs to use for myself since the GeeBoy Turbo, and I only bought that because I thought it wasn't a RIG, but something you'd need skill for to get better items
I wouldn't MIND something like that. Say you play Mastermind, or a Soduku type game, or whatever. The better you do at it, the better prize you get. Makes sense to me.
I did buy the Lucky Star bundles, but that's because they were worth 400k each when I sold them on the marketplace. MUCH better than what I would have gotten had I tried to use them. So no more even buying RIGs for me.
Also, the 90% chances on some stuff? Who are they kidding? I had 9 Famestar 2000, and failed THREE times on the first level. That's not 90%, that's closer to 60%. Which really sucked.
