I just wanted to collect some opinions about this, so here we go:
Think about a military FPS - in wich setting do you prefer it, fully SciFi (like "in 50, 100, 200 years, see Gears Of War, Halo, Quake4) or something like VERY near future, more realistic (like "in 5 years or 10", see Crysis, CoD4, Frontlines)?
This really interests me, as I cant decide.^^

I prefer a completely alien environment. You know how the first time you watch a japanese movie everything is completely out of left field? All the building materials are strange, all the architecture and tools have a certain theme. The customs don't make any sense. Every time you turn a corner, there's some magnanamous decorative castle or odd religious scupltures ( or ARE they?? ). See the TV series "Shogun" and imagine the same scenario on an alien planet.

Realistic sci-fi would be cool, like MASS EFFECT

realistic Environments with some SciFi elements,
like in Stalker.

SciFi Elements are needed at some point, to intruduce unexpected
twists in the Environment,
but too much SciFi make the whole enrironment unbelivable,
and replacable.

Ha Ha...you didn't include my category which is historical, but in the age of guns.

It's an old fart thing.

My FPS ( White Storm ), i´m in creating atm, is a combination of:
- Historical
- Time paradoxes
- SciFi
- Occults
- Horror
- Realistic

A great Mixture.. But in a Story, it fits perfect.

I think I took a decision, but I still want to hear some opinions, so go on...^^

if anyone can make a futuristic version of call of duty, i mean, aiming down sights and all but with a futuristc style, then i'll tip my hat to them... havent seen it yet, oh well, if noone makes it then atleast i i know what my next game may be what am doing is, instead of saying real or futuristic, i'm just developting my own game world which means i have to make my own version to everything, with this, i have small limits on what i put in..

Sounds familiar...^^
Im not aiming for the typical CoD gameplay (with scripted events, endless enemy spawns and stuff), but the general military style, yes....

I'm always a fan of realistic FPS. Even if the enemies are not always human I'll choose Today Modern FPS, not too fond of historical past battle...
But if I have to play any SciFi game, then it has to be 3PS... Especially when the player is a female...
