I am getting old here, a few prolly still remember me, I like it.
Anyhow. Ever since Hawken had its first right-before-death phase I was looking for another game to main. Must say I got into Elite: Dangerous pretty fast.
If you want PvP, be prepared to get your booty handed over. You either win or pay the cost of your failure ... which are insurance costs in form of credits. Yes, dying means you lose progress and if you can't pay insurance you lose your ship. If it's the only ship you have you start from scratch again excluding the achievements and reputation unlocks.
If you don't want to do PvP you can do PvE, trading, lore science, exploring, roleplay or whatever your heart desirtes. In the near future we are getting content improvements for a whole year. New ships, bugfixes, etc. .. there is no better time to start. We also have encrypted spectographs that show un-human navigation maps which aren't decoded yet.
For drop in-out games I recommend Battlefield and The Long Dark.
There are no mech games like Hawken out there but studying IT I will notifying ya'll if I ever get to the point where I develope games. Spoiler: They will be balanced and not easy at all. .. IF I get to that point :p
