There are few things that would cause me to not even give TS5 a chance and VR is one of them. It doesn't make me dizzy or nauseous like some people experience, I just don't find it engaging and get bored very quickly.
If it's optional and enough people want it to justify spending the resources on it, I'm fine with that. I'm just not interested in it and won't play a game where I'm forced to play first-person Sims.
Plus, I'm not going to buy a VR device just to play one game that I know I'll get bored with soon anyways.
