If point and click adventure games run by SCUMM were more popular, I'd say do that please, but I realize the problems with that, heh.
I always enjoyed the idea of a game where you/the main character dives into the internet and experiences different worlds there in. I have really indepth ideas of plot [etc] and everything, but the internet diving thing is all I really need to say to get my wants/ideas out there. I like games that take place in the now and have a sort of normal mixing with the abnormal feel, it really helps me to get into the game and feel like it's happening. I love future games compared to anything else, but I barely ever play 'now/present' games unless they are during some kind of wartime, and some other rare occurrences..
Oh, and if anyone here has played Eternal Darkness for the gamecube, I pray to the drowned spirit of Oblongata that there is a game that runs something similar to the insanity system that game had where the lower your mental health the more silly things occurred in the environment you were in. That was bloody fantastic...if you guys could do a game with something like that in it, I would be so friggen' excited and if I could, help you guys work on it for free. That whole mental health system was so fun.
