It's quite a hasty console port indeed. It's got a few things that give it away, even when ignoring the weird aiming which just feels a bit sluggish.
Scroll wheel doesn't scroll blocks of text. Page up and Page down do.
"Auto-aim" option is available, and turned on by default.
You can't select Sniper Rifle proficiency by pointing with your mouse. Seriously.. Try it.
Mouse sensitivity "slider" is laddered. 0, 1, 2, 3, 4. If 0 is too slow for you, and 1 is too fast, tough luck.
You can play it online, as long as you have a gamespy account. Which is free.

Worth mentioning twice.
It's all very minor in the end, except for the mouse sensitivity. It just gives you that hint of "cheapo", which can take away from your experience. It's like watching the Lord of The Rings trilogy, and during the three movies it's painfully obvious to you that the swords are clearly made of plastic, or one of the character's always shown wearing a pair of Nikes. Doesn't really ruin it for you, but gives you that "meh.." feeling. Kind of like what Yahtzee was on about in his Oblivion review, and the game's problem with immersion.
It's a good game though, and by no means unplayable, unless you're constantly crashing. Just need to look past all the consoleness.
