Great game. But if I may be so bold and offer a little pushback, this is my contender for GOAT video game:
I LOVE this game, and can't find anyone who gave it a real chance and gave it a bad review, and I mean from reading years and years of online reviews about it.
It was also pretty fukking innovating for it's time the way it wove shooters, action, adventure, and rpg elements together to create something spectactular.
If you've never played it, do so. If you have before and can play it now, do so. You won't be disappointed.
Also honorable mention to Gunstar Heroes.
You can't go wrong with either of these games or Tekken 2. Great thread.
