Free to play MMO Roundup:

Planetside 2: Its a fun first person with vehicular combat. Sort of like continent wide domination match. You control certain points to open up a route across the island. That said there is no other point, no end game. There is no “Your side Wins” you just control land and fight for it non-stop.

Pros:
Easy to get into
No need to ever spend money to have fun
Can quickly jump into a battle
Solo works, but your always in a group with local and global chats
Most people have a sense of camaraderie more so here then other games
Pay 2 Win doesn’t exist here

Cons:
Steep learning curve
Can be frustrating at times
Very slow to advance
Poor performance even on state of the art rigs

Hawken: Is a mini skirmish Pay 2 Win mutliplayer game. Its very fast paced and its your basic arena deathmatch with generic modes. Except your in a massive nimble mech. This game is defiantly Pay 2 Win with many items give you instant kill like effects. You gain advancements by fighting, if you win you win a little if you lose you can barely afford to upgrade, unless you pay some $.

Pros:
Games are easy to start up
Games are fast paced
Good for a quick little rumble
Open beta so you can influence development

Cons:
Pay to Win, you don’t pay you will never win
Matchmaking is horrible
Plans to sell game after release to outside company
Infinite lives means griefing, and happen a lot
Its a basic Multiplayer game with nothing new or innovative
Extremely graphically intense game, so much so its not enjoyable.
Sore is over priced on most everything
There is no goal or endgame, its arena multiplayer

World of Tanks: A very enjoyable Free to Play game based around 6 nations. You pick a nation, or all of them if you like and start moving up a tech tree. As you move you up unlock various tank classes. Primary self propelled guns, light, medium and heavy tanks with Tank Destroyers. Each country has there own strengths and weaknesses. And Its very easy to pick up and play wityh nothing, each country starts with a free tanks and no matter what you always win something. As for the end game there is your basic 10 tiers of tanks to progress though in 3 different fighting modes in 15+ locations which are massive. After that there is a global clan war where you fight with your clan to gain control on a world map. Its quite fun and the Devs are committed on adding new maps, modes, and tanks all the time.

Pros:
Easy to pick up and play
Depth to make Min Maxers happy
Enjoyable even after a month, since new content is always coming out
Very fun community to be apart of
Loads of mods for the game
Ability to record and play back your games (record files are ~600mb)
Looks beautiful
One life to live mechanic so it forces teamwork and makes it far more enjoyable.
Store is fair priced

Cons:
Once you make Tier 5 advancement slows down
Can be a little confusing once you start getting into it
Camera is buggy sometimes and may cause issues
Very graphically intense game if you turn on all the dials.
One life to live, so you will die a lot in the beginning, but you always win points.

Mechwarrior Online: Its Mechwarrior faithfully recreated in game. The control scheme is a mix of MW2 and MW3 with the best of both. It controls exactly like every other Mechwarrior game except response is tighter and the engine runs smoother. Based off Crysis 3 its designed for efficiency and it shows, rarely and issue when your melting the face off an Orion at 600meters. Supports all known resolutions for monitors and TV sets. Accepts input from any device reconsigned. Runs like butter on the sun. Very fluid and smooth gameplay.

Pros:
Open beta so you can influence development
Dev team cares deeply for the players and responds with fixes quickly
Very fun and easy to start playing.
You will always have a set of 4 mechs from the 4 major classes for free to play with
Free mechs gain money to buy upgrades for primary mech
Free mechs cycle out, so its kept fresh
Gameplay is team based and it shows, people go out of there way to help each other
There is always a reward for match completion, enough to keep you going.
Like with World of Tanks there is a constant forward momentum

Cons:
Throttle issue when using a mouse as well
Very steep learning curve
A slight pay to win mechanic which can be circumvented with skill
Open beta so there are a few bugs and issues
A long way to go before its ready for prime time
There is no goal or endgame, its Mechwarrior

Interesting round up, I always like to hear other opinions.

You know I was looking forward to Planetside 2 for a long time, but having tried it out in the last month I found it fairly disappointing. Not that I think it's a bad game, just stuck on borderline good!

And I used to play WoT, but eventually I got sick of the grind, and sick of the community. To add to cons, it might be worth adding that the game is in perpetual flux (at least it was when I played), and as such certain tanks can become op patch to patch. Can be a lot of fun though, and quite addictive!

MechWarrior Online is fantastic, albeit buggy. A great tactical game for those who prefer a slower pace and don't like instant death. Well balanced too, so it rewards skill. There are a lot of exciting and ambitious features coming down the road, not least the clan invasion!

If you get a chance you might want to give Blacklight Retribution a go! I've been getting back into it recently. I think it has a pretty good f2p system.
