I think these games are going to be pretty rare. Play-Asia hasn't had any dotstream since the release date and they don't think they're getting more soon. They actually broke up my order of the bit games and shipped the ones in stock because they weren't confident when they would be getting dotstream. Never had that happen before in years of ordering from P-A.
I'm nearly sold on Dotstream. I hope some of you who already own it can bump this in a few days or a week and comment on replayability and if you're still finding it fun and challenging.
