Rage 2 is an open world game that would've faired better as a linear shooter. Every quest, NPC and bit of dialogue is forgettable, shallow and in the worst case, cringe worthy. The game is short, about 10 hours without the 'activities'.
Thank god for the shooting, which feels rock solid. All the guns thankfully are nice and versatile.
There's a good game in there, in amongst all the fluff. You'd be advised to buy this at a steep discount to get your value out of this one.
