Nothing yet. The last time I pre-ordered was FFVII Remake last year.
I thought about pre-ordering FFVII Remake Ultimania... but I already own a few Final Fantasy books and ran out of space to store any more. My issue with these Final Fantasy books is I treat them with extreme care unlike other books... because they're expensive and high quality IMO.
None but when I did it was on Steam and the only reason why was so I could pre-download it and not wait as long to play it on day 1. But those days are dying out any game that is $70 bucks wouldn't get any day one buys from me they can F off.
So far I have preordered Vampire the Masquerade : Bloodlines 2. Hoping it'll finaly be released one day.
I'm also planing to preorder games like Kerbal Space Program 2, Vampire : Swansong, the next Zelda on Switch and Serial Cleaners (indie isometric tactical crime game). Right now it's on wishlist only but hopefuly I can preorder it soon enough.
