One of my complaints with Halo was that the enemies got repetitive, and they are basically who you are fighting at the beginning of this game. The graphics were also outdated by the time this came to PC and it isn't too exciting.
They tell me this is better on Xbox than PC, but I just don't understand what separates this from many other FPSs. The single player mode in this is very repetitive, I feel like I'm fighting the same three aliens level after level and similarly the lack of weapons becomes an issue. On the multiplayer side again, a deathmatch is a deathmatch, nothing overly different. One of those games people either love or find to be overrated. The music is fantastic though.
I didn't get this game until 2011, and despite it being released in 2008, I couldn't help but be disappointed with the graphics. I don't think they are that much better than San Andreas was. The worst thing though is the driving camera. You shouldn't have to move the mouse while you drive, it is ridiculous. it's worth noting also that the driving feels more realistic than the arcadey feel of previous GTA titles.
As far as the positives go, if you like GTA games you won't be displeased with the gameplay. It is what we've had in the past. Driving missions, shooting missions, driving and shooting missions and so on. Again though, whether they have pushed the envelope enough with new features, or whether they have just put you in a new different environment to do the same things gamers have done before is debatable. I feel as it is more towards the former.
This is basically tiggy/capture the flag that gets my heart going as the end of a close round nears. Bloodlines on the PSX is the closest game to it that I've played. Does what it sets out to do well, but gets repetitive.
This game literally takes 5-10 minutes to complete. All there is are 4-5 puzzles to try to find Wally and the scrolls in. I feel sorry for the people who bought this.
