In regards to the last chart, I think that people need to keep in mind differences between EvE and WOW as far as playing mechanics.

WOW rewards users with faster advancement by playing longer. the more you play, the faster you level up. It's a traditional feature of many MMO's.

EVE uses a completely different mechanic, the "Skill Training" mechanic whereby you learn to do different things by training the skill. (IE: Learning to use afterburners on your starship by training the "afterburners" skill, or learning to use small lasers by training the "small lasers" skill, etc.)

The training is automatic once started, and even trains when offline. So there is no need to spend hours and hours and hours grinding rats (or whatever) to level up. Thus, one would naturally expect people to have less raw hours online. While still a very hardcore game, EVE rewards people for playing SMART, not for playing LONG.

So please keep that in mind when looking at the last chart.
