Not even close to finishing the main quest and I'm still liking it a lot. Hopelessly overpowered weapons from around level 15 - which was a bit lame, but still loving it. Just met Virgil and achievement [censored] now. I have all the settlements, even achieved Benevolent Leader which only 1% of Steam players have managed apparently, and I guess it's now time to make a run for the end. Not sure if I'll play it again once completed. It doesn't have the re playability factor that Vegas had for me, so this may be my one and only run.
Saying that, thanks Bethesda for a great game. I has faults, yes. It's lost some of it's RPG appeal to me - yes, but undoubtedly a great game. If I could offer any advice as a loyal customer of yours, don't be so afraid to bring back the more complex RPG elements to the game. It became an arcade game for me at round level 20 - which was a shame.
New Vegas still rules the Fallout world for me and doesn't look like being topped yet, but thanks again. As always, I'm looking forward to more.
