Probably the best game for PlayStation 3, probably the best game i have ever played...
The only two bad things about infamous are its shortness and its glitches. Really it has terrible glitches. For example, after the mission "The Escape" you can't pass the first gate which was full of cops in the mission. Anyway, you can pass it after a couple of tries of jumping to the left of chargeable box. However, the game itself is too addictive, too much fun etc. etc. you just forget about all those things. The best feature of the game is probably the "karma" thing. Because of it you feel like you have to play the game twice. In the first play i chose to be a hero and understood how a sucker i was in the second play. Bad karma is really gives you more fun and it also gives you amazing powers. For example, L1+R2... I never used it as a good but used it a lot as an evil. And grenades, megawatt hammers... In my opinion the only good thing about good karma is L1+R1... You will use this skill regardless you are evil or good. In good karma it heals but there is just a little difference between good and evil about this skill. Because evil gives the "impact". So we can say good karma is more defensive. The game also shows what superheroes and supervillains think. And it also shows how hard it can be to be a superhero. The ending is also very surprising and you just want kick hell out of the last boss.
To sum up, it is a must buy game for PlayStation 3 users. Don't forget it is Only On PlayStation. And thanks to Sucker Punch for making such a good game. Hope the rest will come. Infamous 2 would be great.
