Clearly Kojima should had waited until VITA dev kits were ready, rushing this IP to the horrible PSP hardware was a huge mistake and that shows even more now that it got the HD port treatment.
It doesn't have the MGS FEEL( you should know what that means ) at all, it just feels like a GAMEY version of a MGS game, I really hope Kojima pro is working on a game for Vita which has the power to make the MGS feel come through, perhaps he can make his infamous wish THE BOSS game for Vita.

You say worst like it's a bad thing. If you're comparing it to solely others then yeah it's a bit off on the way it plays out and how it's structured. It isn't really a bad game though. Very entertaining and it's structure allows for easier replayability. Plus sneaking around with a friend is a lot of fun.
