I finally have it, and it’s great. I haven’t completed Fallout 2, but it didn’t affect this game. I created a diplomatic type character with an emphasis on the repair, speech and stealth skills. I also decided to invest in small guns, so I can use sniper rifles. I got out of Vault 101 and reached Megaton. There, I solved a few quests and disarmed the bomb. I’m level 4 right now and I still have much to do in Megaton, so I won’t be leaving so soon.
