Hmm I played and played and played(I could go on with this to enfatize how many I played xD) many games.
For example Bitefight,Ikariam,BattleKnight,Tanoth,Tribos and few others I cant remember I wasnt like OP,OP but was in a decent place specially Bitefight.
Anyways these are MMORPG Browser games, however from what I´ve seen their expensive to get decent gear without paying and there aint any system (at least that time not sure if there is now) for free credits to get the respective (Ingame exchange coin).
I play MagicDuels also since a long time like almost 3years been inactive for quite a while, but its fun to check things around, since I got more or less interested on this game since it helped me with philosophy ;p
I played Flyff had a BillPoster lvl 76, too lazy to download game again since my net is a bit slow and game is a bit big, the graphics are decent for gameplay it allows you to have skins neverthless but the upgrade item ratio and the upgrading cost is to high in my opinion.
I played Tales of Pirates also had a lvl 75crusader, at that time was really hard to lvl them not so easy now that its possible to get over 80 in few hours from what I heard at least -.-, graphics are decent but could be better.
Played World of Warcraft also, the game even thought its payed on a monthly subscription or every three months or six months its a bit expensive since people cant afford it that easily.
The graphics are quite good, at that time I had a end geared level 70 blood elf warlock when cap was still level 70.
I had fun killing the naps in Alterac Valley and get mostly 1st on dmg rank ;P
Currently im playing Runes of Magic, a MMORPG, got a level 62warrior/58priest on smacht server (sadly people consider this combo sucky w/e!) xD.
This game is based on plenty type of ranks to Strenght,stamina,intellect,physical attack, magical attack,etc.
I am on the first ten on the str ranking at this moment.
The graphics of the game are quite good and it offers a free playing game thought however for the extra items you need to buy diamonds(in game exchange coin) or buy ingame,with gold you can farm.
