well.. the MOST important things that MUST be changed in patch:
1) mouse acceleration fix (really, A LOT of people got to "brawl" with this..ehm..FUNCTION)
2) optimization or whatever it named.. i have pretty cool pc configuration, but i had to disable almost ALL lines in video options, because its lagging... so much.. you turn and it lags, you look around and it lags.. these textures that everytime loads again and causes stutterings (if i got this moment right), sometimes they're fatal for some situations in game
MANY people as far as i know just trashed the game, they just gave up on it and uninstalled it immediately, i know. but i didnt
because it has cool action-rpg system.. but again lets get back to lags and cons
i personally thinks that when Mike roll to side from the his hiding point he MUST not stand and run.. if he was DUCKing behind the hiding spot he must roll and move in DUCK position dammit.. i miss many awesome situations in missions when i could be totally uncatched.
furthermore of course i think we need some more customization. if we cant change face of the character ingame we always want to change SOMETHING, especially when it's RPG. then.. we need more haircuts(!), beards and anything else, we need the most customization of the character that we can get from you =) of course without absurd things
ALSO one important thing:
i think many peopled missed it. but we need a dialogue-speed option! or something like this.. i understand that you tried to do dialogues like real with real-timing, but there are many people that are not native speakers, BUT they are really want to play original game with original voices etc. and many of them just cant choose appropriate answer-behavior in-time, ruining their realtionships with characters in game, when they dont want it really..
thats it for now, i wasnt played enough to tell something else =) just two missions in saudi arabia now =)
PS: also the thing mentioned about lockpicking and slow pins. yep this is not fatal or really hard, but we need 'em faster =)
