I just get distracted by perks without thinking ahead a lot of the time. The random levels make it worse. It's extremely fun, but when you're pretty much forced into a play style at times it's just making it make sense to myself.
So, I've seen this game pop up a lot and a lot of the not traditional media seem to scream "you must play this". And from what I've seen it looks fun. I might be able to squeeze out a few dollars for a purchase here soon, so that'll be fun to attempt. As I suck at these types of games.
