1) I paid $2.99 for it
2) that didn't affect me in any way and I didn't notice. Your internet connection sucks balls
3) irrelevant opinion, one I do not share
1) Good for you. I didn't pay full price for it either (I participated in one of the 4-packs, making the game $8 or something).
2) Well you obviously didn't notice then. Your ability to steer hinged on your ping. If you had a 40ms ping, you had an 80ms input lag.
Which, isn't too bad, however, most of the servers in Zero Gear (when I played it) weren't dedicated servers with good connections, the servers were run by average Joes with shitty connections. So, frequently, I had pings of 100ms or more, and the input lag is readily apparent. My connection isn't shitty, and if you looked at the steam forums, you'd see a lot of the same complaints.
3) Irrelevant opinion? Great you don't share it, but a lot of people do. There really isn't an irrelevant opinion when you're trying to get people to play your game. If people don't like something about it, it's likely they won't play it.
Like I said, I really liked the game, and it could've been so much more, but the devs took the wrong approach on a few issues. Not that it would've helped much, as the game would still probably be dead. Who knows.
