Truly customizable characters.
There's lots of games that brag about being able to give you tons of option to make your character unique.
Most of them lie.
I want to make a character that looks like one of my oc's not the other way around.
I want to be able to have a joker looking character with telekinetic powers, God Damn it DC online, I don't want my character to look like Iron man!!!!!!!
..... Oh right, TOME. Well, yes I have seen 2D sidescrolling MMOROGs become crushing sucesses.
I susbcribed to one of them recently and I have been playing it for free for the last four years only ocasionaly buying some game cash now and then for like two or three bucks each time.
With my cellphone.
SECOND THING I would like to see in a TOME MMORPG: being able to buy shit with my cellphone.
It's the only way I buy things online.
Third:
Customizable classes.
Just because I chose a tank type that doesn't mean I don't want to invest a bit on my dex and less on my strength.
