Oh I see.
I tried playing through Half Life, but I just couldn't differentiate between what you can interact with and what you can't. The textures look really dated. I mean, if there was a switch that needed flipping, I could never see it. Lol. It was one of the reasons I never finished it. I thought Black Mesa could help me out there, but it ain't finished yet, so no dice.
Funny thing is, I played the half life games in reverse. HL2: EP2 first, HL2: EP1 next, HL2 and then the first one, lol.
I seem to have put AC: Unity on hold when I decided to play through L.A Noire. It was one of the games I did not finish because of that old HDD failure. I've nearly reached the end of it. Just a few more cases left. The gameplay is really unique. Facial animations are just wow. Side quests are kind of a let down though. I've put around 20 hours into it so far.
