Dead Island 1. Unplayable broken garbage we tried to play online. I refused to buy anything the developer made after that. FOV was disgustingly low too.

Cyberpunk 2077 initially. I was trying to be careful and watched a streamer play the intro up to the montage video. They somehow didn't have a ton of bugs so my first impressions were oddly good. When I played, shit was breaking every single in-game cutscene and well you all know what release day was like. Got caught up in launch hype, should've waited.

Don't have a lot of examples. Usually I'm pretty good about playing legal demos first or pirating initially with demo state of mind. When I can tell I'm going to stick with a game I buy it and restart after a few hours. Occasionally I'll watch a streamer I trust and buy games that way too.

I don't value review sites really.

Edit: I did early days Kickstart Star Citzen, Yooka Laylee, and Broken Age. The classic fuckup trifecta.
