I agree SF setting is getting to boring - however that's due to lack of developer creative effort 'd argue - however I far prefer SF setting to real world.
I just find it kind of odd the rabid desire for many young males to pretend they're winning World War II or sorting out the obligatory 'fictional Middle Eastern' setting.
I don't mind such settings, but they're not my preference, and I'd say these days the real world combat scenarios are now even more cliche than the SF ones.
Personally what I'd like is more well thought out, interesting settings - be they fantasy a'la Thief or a well realized SF setting a'la Half Life 2.
Just like books and movies though, you're going to get repeat and rinse of already used popular settings vs a small amount of creative effort trying to bring you something new.
Try to be reasonable... its easier than you think...
