The friend I sold my 360 for cheap handed back to me for free a couples of weeks ago, really nice
I finally finished Batman Arkham Asylum, loved it free flow is an amazing system. I'm to buy the follow up soon (360 or PC, I've yet to decide) and I wonder about how far they pushed that great fighting system. As it is I see lot of potential.
I love super heroes set-up, DC Universe is nice, but I think the fighting system is lacking. I tried a couple of games that rely on combo within a 3d space, none feels as satisfying as free flow.
So being a H&S person, I wish there would be H&S (isometric type of view) that relies on free flows, a Batman setting would be neat as most characters don't have overwhelming powers.
Another one I would like to try would be another H&S, based on the Mass effect universe, that really on the same mechanics as "arena shooter" (think Gun Bros on mobile platform but pushed to another level: more powers, bigger environments, etc.).
Looting FTW.
