Well, everything in that poll, it's hard for me choose. I don't wanna write an essay describing every single choice, simply what I really like is the very long storyline, with alternative paths, so finally a game where ur choices matters, and the well defined characters, everyone here has his own story, some of them with many shades, that we would like to clear, so I get more and more involved in the game, and hours pass like minutes.
There is another thing I appreciate, the use of the militay therms. I don't play pokemon, I'm also fan of strategy war games, and the use of: choke points, defensive lines etc. really enjoyed me.
