Sense everyone is using Fallout 3 as a example which make sense the game is after all built off Bethesda game engine
so here are the things I think make New Vegas "Better" or refreshing

All bugs aside :brokencomputer:

The focus is more heavy on the sub quest which are more interesting and better written
Societies and faction are the main theme making the world more livelier
Characters and voice acting are more intriguing and have more depth an heart
Iron sight view is a nice new feature with new guns which look and feel more solid
The cool perks are back but there are also some ever cooler perks added to mix things up with that level cap by default is 30 no DLC required! but then again we might see it raised to 50! LOL
And gambling is always a fun pass time in sin city itself Las Vegas which is an epic setting for the series

I'm going to give the game a 4 out of 5 stars :fallout:

P.S.I would say 5 stars but there are to many similarities to Fallout 3 (great game) to merit it as a true whole new game
would it have killed them to create an all new looking menus interfaces hud target system etc. :whistling:

Yes, this wasn't meant to be a whole new game, i think.
It's meant to still be in the fallout 3 universe but at a different time and place, so it makes sense that some things remain the same. ._.
