So what ideas came out of this year's crop of games do you see being copied or should be built upon in future games?
Even if the idea is not really 'new' but the way it is presented in a game from this year makes it stand out.
My nod would be:
SnapMap -- Doom
Building levels is fast, fluid and easy and a joy to behold. You can build complete levels with item placement, mobs and even scripting and logic. One of the many things that make this year's Doom one of the best games of the year.
I hope to see the ease of use that Doom provides in creating new content carry over into other games. Of course most shooters offer modding yet none make it as easy and as rewarding as 2016's Doom.
Special mention to the mod support on consoles.
It is nice to see games like Fallout 4 and Skyrim SE get mod support for consoles. I prefer to game on my PC but it is nice to kick back and game on the 65" every now and then. I hope modding is added to more games and more genres on console in the future.
