During the last year in university, our class had this group project of making an app for Nokia N-series phones. My group came up with Workshop Wrath and it turned out to be one of the many successful apps from our class. However I've thought of some other ideas too which I think are equally good but got rejected. Oh well, maybe someday some of these apps will happen. In other brands of phones.
That's only some of them. There are more too but I feel as if they're either already taken/created or not good enough. And if any coders or game developers are reading this and probably interested in any of them, feel free to contact me and I'll do the graphic designing.
