It's oblivion with guns...but isn't that what we all wanted?
The layout is almost identical to Oblivion with the quick travel, inventory menus, buy and sell and setting up your character. The AI dialogue is also identical. You notice this when walking past a character that seemingly hates you but as soon as you talk to them, their voice alters and they say something very pleasent ha. The swords and shields have been swapped for guns and laser beams and the forest wildlife has been replaced with mutated creatures that look like they belong on Yu-Gi-Oh cards. Bethesda havem't swapped much in the way of how the game handles BUT...this is a good thing.
I wont slate this game at all because it may be a carbon copy of Oblivion BUT Oblivion was fantastic and many people were left craving a gun version of it so fair play.
There are still a few glitches to hammer out (like only being able to close your inventory with the TAB key) and I think the map and inventory could have been made ALOT prettier than just chronic green and black flickering crap.
In summary, yeah this is a GREAT game and well worth investing in, I will be putting alot of hours into it myself but it really is Oblivion without the beautiful terrain and interesting characters.
8.5/10 because I preffered the Elder Scrolls
