Anything that interests me enough from a developer/publisher I trust. Indie games so long as the price is right. I prefer to lend my support to the games I enjoy, because too many games I love are unsuccessful, and some of my interests are niche. I'll wait for a discount if I lack confidence in a title, or if it's too thin on content to justify full price.
Worthy of note: all-out collector's edition pre-order if it's Xenoblade, or probably anything Monolith Soft does from now on.
For multiple titles this generation:
GRID (This one is a bit weird; GRID Autosport was released during this generation but on last-gen platforms)
Need For Speed (skipped Rivals)
Life Is Strange (watched a playthrough of the first, got BtS & 2 at launch.)
I would have probably got Gran Turismo Sport at release if I went with Playstation this generation. Got 5 & 6 at release.
