I dont mind the Larian take on using the terrain to solve combat encounters but I think BG3 is missing the 5E rule spice by a lot. Its still a Larian game so Larian philosophy will be present but the consumer base is coming here for Baldurs Gate and D&D ruleset too I believe.
Every time I've played D&D (3.5, Pathfinder, and now 5E), the DM has been one of those 'environmental' people.
Cast a fire spell in a room with objects that can burst into flames? They will.
Cast an ice spell on wet ground/water? Slippery time!
Cast an electric spell on someone in platemail/chainmail? Have an extra point or two of damage!
Heck, I recall a time we were stranded in a frozen area when our airship crashed. No snow, just LOTS of ice.
So I broke ice off into a pot, put the pot on stilts, and cast Heat Metal; had water for us to drink in just a few moments!
The BG3 having environmental effects does not seem odd to me.
