Well, I wouldn’t want anything like robots and zombies, but I definitely think fantasy has a lot more going for it in terms of potential. In fact, although I know next to nothing about modifying a game engine, I’m already brainstorming ideas for what you’d probably refer to as a fantasy mod. I prefer the term ‘futuristic’, though. It’s more suitable in my case.
I believe a fantasy mod is a little harder to criticize than a realism mod. I’ve been on RtCW/ET forums for a long time now, and I haven’t seen a single realism mod whose realism factor hasn’t been questioned. Even something as simple as a sound mod can’t escape criticism.
