Snapmap might be crap compared to the modding tools we got for the original games, but it's a lot better than I thought it would be. I started a quick map earlier today with the intention to keep busy for an hour or so and then study, and I ended up spending 5 hours on it and now I have to start studying. You can check the map out using the code NNJJ348F (it's about John Stalvern hue hue hue). Might be a bit buggy, but I just successfully played it through from start till end. I'll polish it up when I don't have a massive business management exam looming over my head.
What hampers SnapMap is:
-Asset limits that limit the size of and what you can do in a single map
-The fact that you have to make use of pre-designed rooms and can't get a blank room to add your own walkways, etc. No doubt we'll end up being forced to buy new rooms from Bethesda.
-The controls are very obviously geared towards controllers so it's awful to navigate
-Logic chains break at random and then hunting down the issue becomes a nightmare
-The game can only accommodate max 12 demons at a time and if you place demons on the level, it counts those. This means that if you have spawn triggers, they break if the demons already over makes them go over 12. You can get around this by not placing demons on the map and rather spawning them via triggers, but there should not be a limit and it should not be fucking 12. This is the biggest WTF about snapmap because it means you can likely survive indefinitely on survival coop maps.
I'd say the game isn't worse off for having SnapMap, but I hope Bethesda gives us more control (like that's going to happen) otherwise I don't see myself using this for anything other than throwing together casual maps. I want to be able to fuck players over by dropping 30 hellknights on them in the last room of a level. And then measure their butthurt in downvotes.
