Aren't all FPS's basically the same with you shooting either aliens, undead/demons, robots, or humans? Turok was somewhat original with you shooting dinosaurs.
No, people shouldn't
have to make thir own models. This program was designed for those of us with a)no modelling skills or experience, b)no free time to model or learn how to model, or c)a desire to make simple FPS without spending hours on end to make one. Now, if you want to make your own models, more power to you. Just don't force the rest of us to do the same.
Now is the winter of your discontent.
