I was really unimpressed with Wolfenstein: The New Order. Yes, it did really ambitious things with story and character, but I just didn't think it was very fun to play. I think it's saying something that my favorite thing about it was the title screen music.
In 1999 I foolishly traded in my copy of Super Metroid to EB for next to no store credit. A few years ago I managed to find another copy (or, for all I know, possibly the same copy) at a reasonable price.
Depends. Usually I'll pay just enough (generally $10-15) to get everything if there's enough games/stuff in the bundle I don't already own. I also have a habit of paying just above the Linux average, since they're almost always the highest payers. This last one, I already owned most of the games except for Prison Architect, Race The Sun and Luftrausers, but I went ahead and bought it for $65 because the physical tier (something I don't usually go for) looked awesome.
