Hate to necro, but considering I stumbled on this post on the board's front page while looking at this collection and all, its not so strange an idea that others might as well. Plus its important information to consider, if like the OP you're considering a purchase of these three Fallouts.
Due to the lawsuit war between Bethesda and Interplay, interplay is loosing the rights to sell these three Fallout titles come December 30th of this year (2013). Its not inconceivable that Fallout 1, 2 and tactics will then become unavailable for purchase for quite a while until Bethesda does something with them, should they choose to.
Personally I'd pick up all three here and on steam, and even hunt out some physical copies before that date, as I'm sure their price on ebay will skyrocket until, as I said, Bethesda does something. Something to consider, if you're on the fence on which might be more worth your time. Quick answer, they all are.
