I would say that Gears of War is ranked in some of the better more recent games. I don't think I could call it "the new Halo" or "game of the century" but I certainly think it's a great game. Campaign aspect of it was pretty good, although it could be easily completed in a day on the easiest difficuly but turn it on to Insane difficulty without going on co-op and you're definitely in for a long, bumpy ride. Now, the main reason I believe this game is so popular is because of the online play. People like to get the achievements for this game but many still go back to it even after obtaining all of them, including myself : . Even though there are only 4 game-types, the re-play value far surpasses the need for more game-types (in my opinion). Gears of War online is just a fun and even very addictive game. If you just start playing this game I'd say it would definitely take a while before you got bored of it. Don't get me wrong though, this game is definitely not without its flaws, glitching being a big one. One thing I don't understand is why people would expect a world devestated by war to be so vibrant with colour. There could hardly be bright blue skies without a cloud to be seen if the right mood is to be conveyed. With this kind of game I would have thought more people than not would have expected a dark outlook from any perspective. On a side note, there are 5 Acts to complete in the campaign mode with each act consisting of a number of different chapters.
