What small little thing makes you go "Instant no buy for me" in an upcoming game?

[TeachMeHisty]

My instant "no buy"-moment is when the game does not meet any of the following criteria:
Either
- must be DRM-free if digital
Or
- must be playable offline and can be installed entirely offline (no online checks for authentification, downloads of missing mandatory files, ...) from physical media
- must be complete-able from start to finish unpatched
- must not have major bugs (save deletion/corruption, freezes, ...) or technical issues (no crashed, no major slow-down, ...) for any commonly performed action unpatched
