Recommend me a F2P game

[Electric]

I got bored of it within a week. I guess it's good fun if you enjoy zerg rushes or defending against zerg rushing, otherwise meh.

I enjoy Defiance a lot more overall.

Same here.
I got bored of Planetside the same day I started playing.
I couldn't handle how slowly the characters moved around, let alone while running.
It wasn't an fps issue either as it ran very nicely otherwise.

Never heard of Defiance.
