God loving damn it, this pisses me off so much, the fact that a game such as undertale can practically eclipse a game like Witcher 3. Seriously, Undertale shouldn't even rival it, let alone be in the top spot for GOTY. The game was good, but only good at best, it wasn't groundbreaking, it wasn't anything new. The only thing that stuck with me was it's emotional bits and even then those got a little too pretentious for me.
I played Witcher 3 last year. It took me about 2 weeks to get through. Most distinct memory was wrapping up every side quest I had and proceeding to what I thought was the final battle and end of the game, getting through that battle, thinking it had a kinda stuffty cliffhanger ending, staying up to play through what I thought was the epilogue, it turning out to be the third act of the game, spanning 9 more hours, leading up to a much more engaging and appropriate ending that had me committed to being up well into the morning to see it through to the very end. I thought it was kinda funny at the time. Like the game had taken my gripe at the ending on board and said "You know what, yeah, that is a dumb place to stop. Let's keep going and see what happens!" I concluded the game was a masterpiece in many aspects, visuals, world-building, gameplay, and writing. I was sure then and there it would be my game of 2015. Then the next day I played Undertale. Better luck next time Geralt!
