Fallout 1 was pretty cool, i ran though alot of it and never got back into it.
Fallou 2 was alot better for me, other than the crappy start, I really loved it as soon as I picked it up.
But by far, I love Fallout Tactics, I've replayed that about 4-5 times and never forgot a mission, So much fun and I'd recommend it over the first 2 (maybe even Fallout 3/New Vegas?) Now only if those ghouls didn't have negative perks about being in a squad of humans.
