I have a lot of problems with the online games I have. Maybe it's that I bought them when I did, and my account seems to be more loosely associated. LOL, I don't know. I purchased Sonic the Hedgehog (only partially for my daughter) a long time ago, and these days I can only access the trial version (first 3 levels) even though I've tried to reload my download and even buy a new one on multiple occasions. I just get dumb errors. So my daughter is a master at the 1st three levels of Sonic. lol
Anyway, yeah, if being able to play it offline is the norm, then it's totally worth buying, especially for the quicker loading.
