I've had Fusion for just over a month now (I think). In the stats, it says I have been playing for around 46+ hours.
Most of my internet time is taken up scouring the Official Fusion League boards trying to beat the times on there.
Last night I dusted down my copy of Wipeout 2097 and completed Challenge 1 at around 1am, and I had school the next day!
Is this a case of an obsessed/sad Wipeout Fusion fan, or a case of a very enthusiastic Fusion fan?
