What excited me about RL is the pure sport of it and the insane amount fine grained mechanics one had to learn to get good. Are there any other games with those attributes that that can't be arbitrarily taken away from me?
* Plethora of mechanics and combinations possible, make it impossible for two games to ever be the same.
* Steep learning curve but very rewarding
I am fairly sure it will stay around at least for 3-4 more years (given the current popularity and player base).
