After watching SAO anime , i too decided to start mmorpg .
Final fantasy 14 is a good mmorpg but monthly subscrition is too much for me . So this game is out of chapter.
There are 3-4 good f2p mmorpg game with good amount of player . Rift is probably the only f2p which is old school type and doesn't restrict players just because it is free . Game is around 8 gb and it is similar to WoW .
Another game is Tera . Probably the best looking mmorpg game out on pc. Game size is huge, around 16gb download and it focus more on action and combat . Though its not upto Rift level , still its a good f2p game .
Another game that come in my mind is Star Wars kotr . Although f2p , but it is very restrictive and encourage you to buy to enjoy it fully . So i wont recommend this but if you are star wars fan, you can try it. Game size is around 20gb.
Lastly , there is Guild wars 2. I think everyone have heard about this game . Although its not f2p , but unlike Wow and final fantasy 14 , its B2P , meaning You have to pay one time only. This is my favourite mmo game and i am enjoying it daily. Areanet release new content every 15 days , so you can say ,it doesn't have end game. It is available for 1.5k-2k .
I would love to play with you guys if we can find five or more member. We can make new thread discussing time,players etc . You can choose any mmorpg but personally i will recommend Rift . Because it does restrict you much . If you decide to download it, then download from steam so that we can communicate easily .
