For now, it's Skyrim. It's very well-designed. The immersion is very strong and most of the game components don't break the immersion. Those components don't remind me that I'm in a game. It's very good, unless the inventory system. It pauses the world when I use it. Kinda ruining the immersion, even though it makes it easier to survive. The character creation is good, and other stuff.
Mount & Blade Warband. I also love that game. It's very realistic and open, even though the technology is somewhat outdated. You can make your own army, get companions, upgrade weapons, and stuff. The character development is balanced as well. It's very RPG-ish. The game is very open and flexible. You can also find a lot of mods, like Game of Thrones mods and stuff.
I also love Monster Hunter. The world is very attractive to explore, and the hunting experience feels very real. Legit monsters, items, weapons, but the game can get boring after awhile, since you're just basically lurking in the same areas over and over.
I think that's all I can remember at the moment.
The theme is very depressing to me. Reminds me of death. ;_;
Very good game, though. It's thrilling and the combat thingy is very different than most zombie games. It's not just about blasting the shit out of massive walking corpses. It requires skills. dat hearing sense
The concept is very cool, having an entity and stuff, but the gameplay is horrible. Game designers back then had tried making movie-like games and they failed very badly, and David Cage is repeating it, just with a better technology.
