I've only completed one Saudi mission and I love it so far but it really needs a level of PC polish. A lot of this is repeated earlier in the thread but I wanted to voice my support of these suggestions. I'm a big Obsidian fan, so please read this as my support to make this great game even better.
Quick Save - no really, forget the dramatic choices argument, let us play the way we want to play. Nothing worse than having to reload a checkpoint immediately BEFORE a hacking mini-game multiple times. Another great reason, you can't save at the safehouse after buying from the clearinghouse or changing inventory until you start a new mission.
Multiple Careers - Starting a new game should not overwrite my previous game's saves. Simplest example: Mass Effects.
If you insist on solely keeping the checkpoint saves, please allow a checkpoint save from the last mission. I accidently ended a mission before I wanted to by finding the main objective before I was ready to leave, not knowing I would teleport back to the safehouse as soon as I clicked it. Don't overwrite mission checkpoint saves with safehouse saves. Actually, save every checkpoint from the current mission and the last safe house separately.
Camera Distance - it's a tad too close, please allow us to zoom out a tad, some of the camera control issues go away with a little more wiggle room.
Hacking mini-game - Enough said?
Dialog Timers - Defaulting as current is great to encourage dramatic conversation but you'd make a lot of people, including those with reading disabilities, a lot happier by allowing longer timers or better yet an option to turn the timers off. I realize the stamina system is tied into the conversation timers, you can still only allow the same amount of time to pass in-game as the current timer does.
Smaller fonts in the character, intel & other screens - when I can only read a few lines of text when I'm sitting 18" from my monitor and then adding a "more text" button, that reeks of console carry over.
Mouse wheel - should work for email, intel & skill texts. Anywhere where it has those tiny up/down arrow buttons without even a scrollbar to drag, the mouse wheel should work. Dragable scrollbar added would be a nice bonus.
Escape key - gets you out of the current menu/screen. I think right click somewhat functions like this already but come on guys!
Quick keys for powers - a bar that shows the quick keys and or weapons & gadgets would be fantastic. Your own NWN2 did a fantastic job with this, even adding additional bars in later patches. That was much better. This is really pretty standard for PC RPGs: Mass Effect, Deus Ex, NWN, etc, etc. Go ahead and make it like the companion menu in Mass Effect where it only popped up if you held a key down as an option if you're worried about immersion breaking.
Corpses stay - corpses shouldn't disappear during a mission. Added as an option is fine.
This is a great game and thank you for all your time and effort!
