even the 360 had a doggle that lets you add a mouse /KB its amazing with some tweeking (dont even think its close to a M/KB on a pc, its not) how you can own console gamepad players on some games. Non stop "hacker" comments. I love FPS and sadly my age has somehow told my reflexes they are getting no more love and will not improve, but actually get worse as i age.. on the PC where its equal footing (M/KB) i can pretty much hold my own, but never dominate.. on the 360 with a K/M (dongle) and far to much tweeking.. i feel like the old days.. its sorta like driving a MECH.. in PC games you turn left, its a mater of how fast you move the mouse.. on 360.. dont matter how fast, it only goes as fast as the game allowed.. (like a delay sort of) but the mouse eliminates my "fook, i cant get my up down targeting skills , left right.. no problem,, but im shooting the ground in front of him, damn now im shooting over him"
not many places selling um nowdays, market was not there i guess. XIM still makes one i think.. there where a few others (better) but you can only find um on EBAY nowadays.
but that wont help you with RTS games that are not made...
