You can play a few more games other than this one, and they will all equally share the same amount of fun and joy as when you've never discovered the game at all. On a case to case basis. I think.
But if you take up the mantle of becoming a fighter here you will live the rest of your days in endless toil, the light of day will never find you, and time becomes a blur proving nothing more that your existence is an abstract amalgamation of electrical impulses in your brain.

This is a game of classical music, migraines, nightmares, and the sliver of time for taking a gander at what little luck supposedly supplies your dopamine/serotonin intake. It won't be easy, but suprisingly it won't be too difficult. But then again, that depends entirely on the way you see it. Challenges make humanity.
I played since launch and as insidious as the discrepancies between servers goes, don't listen to everybody. Not even me. Play the game already you twat, and be the King of the Iron Fist Tournament! :^)
