I really liked the Cognition series, but then again I'm also someone who is totally willing to forgive the adventure genre issues because I've played so many. As such, your mileage may totally vary. Erica's special senses do get some pretty cool usage later on, though.
This is a really cool idea! I am honestly now considering doing something similar (albiet, my schedule would probably need to be 1 game a week versus 1 a day). Still, great stuff and I look forward to seeing which games you play or shelve for later.
