Love playing games, but I can't play them for long periods of time. About an hour and I need a break.
Most games I'll play for about 4-5 hours, love it, and never have the urge to pick them up ever again. Then again, I played a lil bit of CS back in the day, about a 1-3 hours a day, and currently I'm playing a lot of LoL. Probably about 3-4 hours a day depending on how the server is doing and how I'm feeling.
Games are usually 35-50 minutes, so I'll play one, take a break for an hour or two, then play again and so on. Normally though, my attention span for games is like 20-30 minutes and I'm done for a bit.
Books on the other hand, once I pick one up, I like to read them in one sitting, kind of like watching a movie. So, once I start, I usually don't stop till I'm done.
