For myself I find the turn based system better than the real another FPS game system. I find it funner having to plan out what I'm going to do instead of just running in and shooting everything like it's CoD. For the atmosphere

I like the rebuilding theme the first two games has better than the destroyed world themed Fallout 3 and NV went to. In Fallout 2 there's Vault City which is a newly built city and in Fallout 3 and NV there is no such thing. All you see is shitty built settlements or people living in an area that's already existed before the nukes.

For Fallout 2 to me that games has harsher choices to it. If you become a slaver you end up fucking yourself over and then there's the Ghost Farm quest. If you're too late or you have that farm village attack it then everybody in the farm village is dead to you. Every NPC there ends up only talking about the attack or whatever. Even the people that sell you things loose that ability once you or they attack the Ghost Farm.
