I never played Fo1 Fo2 or Fo:Tactics and I still found Fo3 one of the best games I have ever played.
If you are interested in an Action/RPG/FPS. Then Fo3 will be your messiah. It should keep you occupied as I have had it all year, played it alot of times, and have still not explored or experienced half of it's content.
Yes, totally agree with this. Fallout 3 was my introduction to the Fallout series, and it was, and is still, my favourite game of all-time (and I include Bioshock in that!!).
You don't need to have played ANY previous Fallout games to understand Fallout 3.
Fallout 3 takes place in the same game-world, but it's located around Washington DC and its suburbs, whereas Fallouts 1 & 2 are located mostly in California and Fallout: New Vegas is located in, well, Vegas.
My advice would be to play Fallout 3 first.
Some further tips:
1. Do NOT assume that you HAVE TO do anything! In other words, feel free to follow the Main Quests OR just go off on your own and explore. In FO3 you do what you want, when you want and how you want. That's the magic of free-roaming RPGs. Take on Side Quests whenever they present themselves. The Side Quests are more varied and interesting than the Main Quests, IMO.
2. Do NOT read the Fallout wiki. You will completely spoil the game for yourself. Fallout 3 holds such magic memories for me because I was totally new to the series and knew NOTHING about the game before playing. The result was an unforgettable journey of discovery and adventure.
I have 13 full playthroughs of Fallout 3 under my belt, totalling almost 2,000 hours ..... seen it all, done it all. If you want some questions answered, feel free to send me a Private Message and I'll help if I can.
One more thing .... have fun :flamethrower:
