Exactly as the title says. What are the Xbox series/games that you want to, but, for whatever reasons (lack of money, not owning the system, laziness, etc.), never got around to trying/buying? List the franchise/games and the reason(s)you want to play it, as well as the reason you haven't yet.
For me, the biggest series is... uhh... Crackdown I guess? Most of Microsoft's series' that I was ever interested in I've already tried, not to mention that they don't exactly have as much as Nintendo or Sony.
I've always thought that I would've liked the idea of a superpowered sandbox game, but from what (relatively little, admittedly) I've played of InFamous and Prototype, I wasn't particularly impressed.
When we go to individual games however, things get more interesting.
I've played the original Banjo Kazooie on the 360, and was SUPREMELY unimpressed by the controls, by I was still want to give Banjo-Tooie a try. I have Rare Replay, I'm just lazy.
I thoroughly enjoyed Fable III, and really want to try Fable II (and am well aware of its reputation as better than 3 in every way), but I'm lazy.
One of my good friends heaps praise about Blue Dragon, and I'm willing to give a shot on that alone, but lazy.
