Oh man, I haven't come onto this thread yet because I knew I'd be too jealous.
Not only will they never do this on the Wii, if they did it'd be the biggest pile of sh*te ever.
I love the Wii, but it's so outdated compared to the new generation of consoles.
Two and a half years after posting this, I've got it!
Downloaded it cheaply and just started the Marine missions today, loving it so far!
I can understand the criticism it has received, there are plenty of flaws, plus being able to "fight" with an alien and just knock it down over and over is absurd. But having loved the films (not the AvP films, the originals) I was clearly going to enjoy entering this universe!
Plus, after playing Skyrim to death, I needed some cheap thrills and linear gameplay to chill out!
This is perfect, go from A to B, fight a bunch of aliens, watch a bunch of Marines get killed, awesome stuff!
