I love going to E.B games. I could spend hours there just browsing.

I buy some from eBay too.

The Phoenix Wright series. Takes about 1-2 hours to finish one case. There are 4 cases to each game. 4-8 hours. There are four games (including Apollo Justice) so that's 16-32. Mind you I was using a guide so maybe even longer than that.

Also spent a lot of time on Pokemon Pearl and Custom Robo Arena.:D
