Acclaim was most famous for their wrestling games. Every wrestling game they turned out was pure gold (at the time at least). Since acclaim lost it's contract with the WWE about midway through the n64's run, wrestling games took a major hit and are just now catching up graphically to what they used to look like when acclaim had the reigns. Yes, we are on a whole new generation of consoles, but once you take away the gourand shading from the current models they are barely as good as the ones on WWF Attitude. Crapfests like aki and anchor currently have the liscense and after their 5th or 6th game they are getting it right.
Acclaim also produced the console ports of the original mortal kombat and I believe the sequel. Yes they are midway games, but without acclaims financial backing they would have never made it to home consoles. (At this time midway was about to go under. So in a round about way acclaim saved midway along with mortal kombat.)
They are most recently know for ruining the star trek franchise, although that is a falsehood and their two "Elite Force" fps were quite good.
And then there are the slew of other titles already mentioned in this thread.
My point is if you think acclaim is a bad company then you must be too young to remember gaming in the early 90's. Acclaim ruled the market and were a great company. They were the kings of taking a sports or movie liscense and actually making a good game out of it (something we can't even do today.) Remember the batman and batman returns beat-em-ups? They made those.
Acclaims ONLY fault ironically is their dedication to quality. In the mid-90's various liscenses got fed up with acclaim for taking to long to produce their (insert name of celebrity liscense here) game. The liscenses soon stopped coming except for the really bad ones, which demanded a near-impossible turn around. This resulted in the one thing that acclaim never wanted.... rushed, crappy games. When acclaim resurfaced on the pc market a few years back this trend continued.
So don't blame acclaim for the horrible Olsen Twins game, blame Mary Kate and Ashely and their inability to understand a GOOD concept for a game and how long it takes to make a bad concept into a good game. Don't blame acclaim for that slew of bad star trek games, blame paramont, who demands a "fresh new look" (read as new game engine) for each game and a year turn-around, which is impossible if you want to give the star trek franchise the true "nerd-like" attention to detail it deserves.
In the future, don't be so quick to judge.
