I tried to play it recently and I just couldn't do it. I don't know why, maybe because I wasn't fully confident in the controls, etc. I may try again in the future, but for now it's a no go.
Yes, I am impressed by the previous versions of this game. After playing the latest versions of Fallout (3,4), I thought that I must check out the previous versions (1,2) of this game and I must say that everyone should try them.
I loved the first Fallout. I'm not sure if I like the older gameplay style or the new one better, but both are superb and it just speaks to its quality that I can't decide.
