Can't sleep, Too early?!

A night that I can’t fall asleep. Is that too early for me? May be, cause I have been slept very early these day, almost 3 to 4am! What did I do? People said scumming, what does it mean? play TV game, Xbox. I haven't been played for long time, I am now playing a fighting game, don't know it should be classified as RPG or not, it calls Marvel Alliance 2, most of Marvel Heroes appear in the game, such as Iron Man, Captain America, Spider Man, Wolverine etc, it is a really addictive game. Player selects 4 heroes to form a team, then try to complete different missions. You can combine heroes power to perform a great damage attack, so fun, and there are a lot of locked hero and feature waiting for me to unlock, that's why I spend almost 5 hours per day to play. Oh, no, I am writing sometime I didn't expect to write, never mind, I will write it
