Im sorry... im going to pay for them... i dont pirate what people worked for
I got the three games (Fallout, Fallout 2 and Fallout Tactics) for $20 as a bundle on Steam. I'm currently doing my first playthroughs of Fallout and Fallout 2 - once I finish them I'll start on Tactics.
My Fallout character is currently Level 5 and is doing quests in Junktown. My Fallout 2 character is Level 9 and has just arrived in Broken Hills. I'm really enjoying both games a lot. The gameplay is very different than that of Fallout 3 and New Vegas, but once you get the hang of it, you'll do just fine. The first enemies you'll encounter are very easy - they'll give you some good opportunities to practice with the combat system and gain XPs. They get a lot tougher quickly, though.
If you get the Steam bundle, you'll probably have to patch Fallout and Fallout 2 to get the graphics to work properly on your computer. But there are several methods out there to patch your game and they're all easily implemented. I haven't played Tactics yet, as I mentioned, but I did launch it after installation to make sure it worked, and the graphics seemed to be okay "out of the box" on my computer.
One mod you may want to seriously consider for Fallout 2 is the Fallout 2 Restoration Project. It fixes a ton of bugs, patches the graphics and adds a bunch of content that was cut from the vanilla game. You'll find information on this mod, as well as other patches for Fallout and Fallout 2, on the NMA (No Mutants Allowed) forums.
