yeah I don't really get the hate, people just like jumping on bandwagons I think. i don't think you can name another FPS (or engine rather) that isn't PS2 that can support two hundred man servers with an easy 80 FPS on ultra settings in pre-alpha/alpha aka not fully optimized game. the melee system is pretty fun I think, definitely better than rust but that's not hard to do. the bow feels good, i haven't really touched the weapons yet because of the bow being too much fun, shotgun seems like the overall best from what i've heard and seen. weakest point in the gameplay would be the vehicles I think. poor handling, flip way too easily, blow up on the tiniest obstacle, ect. we've also experienced some items disappearing from our storage crates, which was infuriating because we were about to repair a truck... until the sparkplugs vanished.
they've come out with patches each day so far fixing each of most complained about features, offered a no-questions-asked refund to anyone before Monday (so they're losing money each refund), ect. seems like they're doing a fine job to me.
