I somewhat agree with the OP, there are some very basic issues that have been around for months that still haven't been fixed, i'm not a programming expert but i know enough to be dangerous, and im sure with only a few hours of work these things could be fixed...
This happens with all games, once it's released and theyve made their money, they dont give a shit.
Thats why all games need to be "pay per month" or whatever, so they still make money over time, otherwise the developers never do anything after release.
All in all, this game isn't very fun after you've played for a few weeks, there isn't a lot to do, leveling up is basically pointless, most perks are useless, and "vanity kills" on jason are meh, plus everyone was given a few 13,000 CP which was enough to basically buy any you wanted.
Would I buy the game again? Probably, but not for 40$. 30 tops.
