If I jump on something at release / for full price, it's usually retail adventure games I feel like supporting (with Kickstarter there's less and less "loose change" for that lately though).
Last one was the 'collector's edition' of The Book of Unwritten Tales, before that Black Mirror III, Botanicula (although that might have been on some early discount, can't remember), Tension, both Darkness Within games, Experience 112.
Also pre-ordered Gray Matter. Oh, and the boxed Resonance.
My last (and possibly first) digital at-release-purchase were the remastered Sherlock Holmes Consulting Detective games.
