I will tell you why I play MWO :
First of all, the action is "slow paced" compared to other action games or shooters. I don't get owned by swearing 12 years old hyperactive kids on a sugar rush.
Slowness offers much deeper tactics when playing with friends.
I can play with any friend, of any level. There is no "you must be -this level- to enter the dungeon", and no stupid quest lists forcing people to go different areas even when they are the same level. (I am looking at you Generic WoW-like MMO. *frown*)
It is actually easy to fully equip your first set of 3 Mechs variants in a week with every skills. The rest is pure horizontal progression.
Games last 15 min max. When I die, I can chat with my friends, take care of emails and other stuff without being forced to pay 100% attention for hours.
There is no respawn/repair mechanics. When something is shooting my back, it mean he managed to tactically outplay me. It is not a random dood one-shotting me from behind because he spawned in my back.
The rules of the game are fairly simple once you know them. Every lasers behave the same, every armor, every engine... beside a few hardpoints and hitboxes positions, it is very hard to call a mech unbalanced. There is no need to learn the 5 skills of every 119 heroes in-game plus every item combinaison.
Compared to other popular games, MWO is very simple and most rules are logic.
There are many other reasons why MWO is a unique game that fits my playstyle. The point being I couldn't find a better game for me. (And I don't even like giant robots or battletech)
Cheers,
G.
