hey i had the exact same experience with those 3 games xD also bulletstorm. its fine if you have a lovely perfect internet connection, but those games are the kind u play when you dont have a lovely perfect internet connection.. sept maybe dw2, but ret doesnt use it
also for this one etextbook i bought (actually rented) i have to use "CourseSmart"'s proprietary reading interface, which is just awful. if you dont make sure to turn off the app before you disconnect from the internet (so that when you restart the app you can login in offline mode) it will delete the book from your tablet. So basically if you walk out of wifi range it deletes the thing that let you still read the book if you were to walk out of wifi range. Then do you just redownload it? no of course not, you only get 1 download per device, so you have to call tech support to have them reset your download limit to be able to download the book their shitty app deleted in the first place. Thats not even touching on the fact that the actual reader itself is just a crappy version of ibooks' pdf reader, that uses twice the power. Ive never burned through a full battery charge with ibooks, but itll last 12+ hours of continuous use at 100% brightnes; the coursesmart app is 6 hours tops
i ended up just getting the pdf version of it (not from the publisher) and reading it through ibooks, so i can just read the book i paid for instead of going through all the publisher's bullshit
