Anyway, I completed New Vegas over a week ago, and to be honest I stopped straight afterwards and I'm going through yet another obsessive Minecraft phase.
The joy of delving deep into unadventured caverns and hunting for rare ores... and then a creeper comes out of nowhere, scares the crap out of you whilst killing you in the process. Oh, and by the way, I learned my lesson... my house is now creeper-proof.The final battle at Hoover Dam found me siding with the NCR and Rangers, mowing my way through Legion troops and reaching Legate Lanius' cam p. That part was extremely difficult as (with the combonation of an urgently low supply of Stimpacks/Super Stimpacks, damaged armour and Legate Lanius himself who lopped off a 3rd of my HP every hit) there were snipers everywhere and the Legate himself was a formidable foe. In the end I managed to corner him behind a wagon with a crippled leg. From their I destroyed half his health with a trio of Plasma Grenades and finished him off with my Ballistic Fist... it was awesome! :)
Luckily I saved before the Legion commenced their attack on the dam because the story ends completely and restarts you at your nearest save! I still have plenty of quests to complete and many, many places to visit. Before I finish that off, however, I'm returning to the sweet, sweet world of Fallout 3 to find every location, collect every weapon and do all there is to do!
