Rust is cool and all but it's very basic looking and a little buggy at the moment. It can be quite fun and rewarding but it's very repetitive and servers are frequently wiped. There's always a bottleneck for higher end gear, namely C4 which can be ridiculously hard to get until a certain point, and then everybody has it. This can leave several people/groups having a ridiculous edge compared to other players through pure luck.
Quite honestly the lack of content updates pisses me off considering how little the game has changed since the initial release and how much money they have taken in. To me it looks like they don't give a shit about putting much work into it. Cheating was rampant for a long time and cheaters were pretty blatant and brazen about it and made no attempt to hide it. Who knows maybe they are working on a refined/polished version and it's more of a proof of concept at the moment. I definitely got my money's worth out of it in terms of hours played but I have zero interest to play at this point. Maybe if they actually make some worthwhile additions since, you know, it is in development, I could be swayed to come back and play, but it doesn't matter to them. They already have my money.
