FPS (First Person Shooter) and RTS (Real Time Strategy), might want to explain what those stand for, only the first time is good enough. And instead of Q3 maybe use Quake 3, obvious for you and maybe but probably not for all readers.
Some other little things, for example Dragon should be Dragoon (I think..), and there is a lot of bold text, code seems to be filled with <strong> tags for some reason?
Maybe bring in some aliens? A few screenshots or artwork might help keeping people interested and continue reading.
Looks good other then that, learned some things being a new player myself, keep up the nice work!
p.s. btw iirc idk stands for i dunno imo oknp!
