Both Pacific Rim games are terrible, by all accounts, which is totally unsurprising yet disappointing nonetheless. You'd think someone would be able to make a decent video game out of giant robots fighting aliens.
Don't worry though -- if you're into Jaegers and mech and all that jazz, there's a video game that's well worth your time: Xenogears, a role-playing game originally developed for the PlayStation 1 (and downloadable on the PlayStation Network to play on PS3 or Vita).
Xenogears is great not just because of its wonderful music, stirring story or sprawling world -- it is great because it lets you pilot giant robots, and use them to beat up A) giant monsters; B) other giant robots; and C) god.
1) The text speed is very, very slow, which is kind of unbearable when combined with the fact that...
2) This is a very long game. It takes something like 60 hours to finish.
BUT. If you've got some patience, and some fortitude, this is the giant robot game you've always wanted. When I saw Pacific Rim this past weekend, all I could think were things like, "I wish this movie was about Xenogears" and "Now I want to replay Xenogears." So check it out.
