Basewars: I'm pretty sure this was the first and only fun baseball game ever in the history of video games. Konami needs to remake this fucking game now and maybe even do it with other sports. Wouldn't be a bad way to edge into EA's horrible sports game monopoly.
Treasures of the Deep: A very underappreciated and underrated, but completely awesome game. It deserves a sequel badly (though I can already see Bamco milking the DLC on this one, 300pt. paint jobs anyone?). Oddly enough, it's the only good game Black Ops ever made.
Colony Wars: True, it had two crappy sequels, but the original had some of the best production values I've still ever seen in a game. The James Earl Jones-esque narrator, the very in-depth menus, stats, and background info and really awesome graphics for the early PS1 years were way ahead of its time. A faithful remake of the original would absolutely kill on this gen of consoles, though some extra content wouldn't hurt.
Tetrisphere: This was my favorite puzzle game of all time, and I'm still shocked they never went further with it. Sequel, DS port, Wiimake; I don't care, anything will do; just bring this damn game back to life, Nintendo!
Deus Ex: So far, one of the greatest games of all time has only gotten one decent, but very misguided sequel. I'm well aware Deus Ex 3 is finally being made, but I'm pretty sure it's gonna suck, so I'm still putting this on here for hopes of an excellent sequel, or at least remake, down the line.
Also, awesome call on Uniracers, Novax.
Jam it back in, in the dark.
