Just finished my first playthrough and was up until 2 a.m. going straight through it. *spoilers ahead**even though nobody is here spoilers are ahead*
When I got to the part with Lugo being hanged by the locals I was really tired and just wanted to finish the game but these darn locals were in my way! I honestly was so tired that I hated these people for getting in the way of my mission. I grimaced and took those civlians out and felt good about it. I think I felt as one with Walker at that point and from that point on I was a remorseless f****** killing machine.
I had to shoot myself at the end though. It was the only option for me to retain my exhausted sanity.
Yep, I finished the game originally at 3AM, finished the last half in one sitting. It helps because you are in a similar state of mind to the character, who has also been up for at least 24 hours. I too gave into darker impulses and gunned down EVERY person in that market for killing Lugo.
I guess the best way to describe Rez is if a DJ game and Star Fox had a baby, and that baby was on acid...
Weird similar thing happened to me. By the end, I didnt care about anything or anyone I just wanted it all to be over with already. But not really, because I loved the game and wanted to keep playing, but you know what I mean.
Pros: The pills were there. Cons: So was the tank.
