In fact, I should also include
Conflict: Desert Storm as my second vote.
After playing Metroid Prime and completing it, I'm slightly stuck to the button system. I liked the way how it was all so comfortable and had no overlay on it.
Desert Storm however

I'm trying to get used to it and I'm getting nowhere. I can't see where I'm going in the game, the radar is practically useless. The graphics are somewhat mediocre, but generally lacklustre.
You can't see who's shooting at you! All you see is a slightly thickened yellow line head in your direction then after a second it disappears. The engine seems pointless. Someone was playing the game along with everyone else at the time, then he just 'fell' out.
My friends like this game, but I find it so badly crafted it's a nightmare to play. The vocals are awful.
The 'sand' in one of the levels was simply just a sand-like colour repeatedly hazing the screen every second. No detail now was put into this, because all the characters see the sand at the same time.
Strange considering wind currents can change when you are in different places?
Not like Metroid Prime where it hazes when you are standing in heat spots, then when you leave them it returns to normal view.
Simply awful.
