EF2:
Pros = Sweet SP, awesome weapons (with alternate fire modes!), great voice acting, and the Q3 engine has never looked so good. Lots of different environments and good atmosphere. All kinds of StarTrek creatures to fight and talk with, and you can use the tricorder to do tasks too.
MP is cool. Weapons have great visual effects. Most of the maps are done well too; some of them seem to have Q3A type layouts... but better.
There are even mutators like in UT(2k3).
SO, there is lots of ways to play.
They just released the development tools as well, so expect to see some cool stuff coming around.
(You could always map for it out of the box, though).
Finally, the game gets super high fps with the details cranked all the way up at really high resolution.
So if you have a halfway decent system, you are gonna see this game as it was meant to be seen... with no slowdown
Cons = SP is too short (I only say that because it was soo fun). In fact it gets better and better, and ends at the crest of coolness, which could be percieved as either good or bad (ending on a high note can be a good thing for a game).
The weapons are not balanced very well for MP (still hellu fun though)
Some of the SP AI was stupid, some of it was pretty good though. I guess AI is a tossup.
Also, while the game looks great, dont expect UT2k3 poly counts or anything like that.
The lighting, visual effects and textures are done REALLY well, but the stencil shadows were buggy, atleast on my ti4600 card (stencil mode might look better on an ATI).
I do remember a couple drab looking levels however, like the Borg ship.
I remember it looking better in the first game, but I might be wrong (it's been a long time since playing the first).
It is from a different developer this time...
I can only imagine how awesome the next Trek game would be on the Unreal engine
This is all I could think of right now. Haven't played online yet, but you can have bot matches to practice the weapons and maps.
Most of the online reviews are pretty spot on, giving it high scores (average of 8 out of 10), but dissapointed at the short SP experience.
I agree, it's a great game, and better than the first (longer even)
(just so you know, I paid full price the day after it was released, and I don't regret it. $20 is a steal *thumbs* )
