timetopat: I know the game gets a lot of hate from fans(Some more than fo3), I was wondering why?.
The problem is two-fold. First of all, it's not the best squad based tactics game out there. It's a good game, but it's not the second coming. Which means that if you're a fan of squad based tactical games, FO:Tactics may fall short of expectations.
Secondly, it's a Fallout game in the same way Galaxy Quest is a Star Trek film. Which means that if you play if for the Fallout fix you'll walk away unsatisfied, because this isn't Fallout as you know it.
The former is a problem because there's better, older squad based tactical games out there. The latter is a problem because most people wanted more Fallout, not Fallout piss-takes. If you're prepared for the latter, however, and you've already played the best 5 squad based tactical games to death and beyond, you very likely will enjoy FO:Tactics.
It's not that the game gets a lot of hatred from Fallout fans. Generally, it doesn't. It's just not the best game ever, and as a homage, it falls apart at times. Thus, it doesn't get a whole lot of praise from Fallout fans. Personally I like it. But apart from this post, not so much it ever inspired me to rant about it online. Gauging reactions in other communities, most people share similar feelings.
