FallOut4 - 8/10: Solid and entertaining, but very easy to become so rediculously overpowered that literally nothing can threaten you.
The main offending builds are stealth/sniper and maxed out power armor. Stealth/sniper means you basically oneshot every mob you can engage from range. Maxed out X-01 power armor (the best suit in game) makes you so insanely durable that you can literally stroll right into an enemy base and obliterate everyone without a care in the world. You will do more damage to yourself with the careless use of your own explosive weapons than the enemy can ever hope to do to you.
Towards the end of the main story campaign when i decided to wipe out the Brotherhood, i was strolling down the main corridor of their fortress murdering everything with this godly OP assault rifle i had crafted like 25 levels prior. All these guys in power armor were dying like flies left and right - when it dawned on me that there was no challenge left in this game. I immediately began to lose interest. I did finish the campaign for the faction i chose to support, but the ending was pretty anti-climactic. The journey was fun though.
