Recently I tried to install a free MMO called Perfect World, and boy, was it awful. The game had to go through no more than 3 installation processes, and canceling any of them at any time would make you have to go back to the beginning. Not only that, but the game takes up about 8 GB by the time it's all done, and half of it are in files you will never use. Also, it makes you think at several occasions that you're missing key files, but really you aren't. Checking for the missing files will freeze or slow down your computer, and takes twice as long as the original install. Then, after all that, there's a patch and update that ALSO has to install files to your PC, taking up more space and time. I gave up and deleted it because I just didn't want to find out after all that the game wouldn't play.
