Is that a good thing or a bad thing? GameThrill - that'd be good. GameSwill would obviously be quite bad. GameChill? Could be cool, but coudl be rather off putting (especially if you're used to GameSpill - where a game has far too many bits).
game chill (n.) 1) a tingling sensation felt when first seeing stunning, promotional artwork for a much-anticipated game; 2) a tingling sensation felt upon discovering a before unknown release date for a much-anticipated game; 3) a tingling sensation accompanied by shaking hands experienced when opening a new game and seeing its components.
Synonyms: geeking; salivating. Usage: "Harrelson experienced a gamechill when he saw the new Sensei cards for Ninjato."
Additional acceptable definitions - really just gamechill used as different parts of speach:
gamechill: (v.t) to cause gamechill (i.e. 'Ninjato gamechills Harrelson.' or 'I am hopeful that the Ninjato images on BGG gamechills enough peole to elicit multiple pre-orders.')
(adj) to be characterized by the elicitation of an enjoyably perceived tremor, parasthesia, palpitation or diaphoresis (ie. 'I fear becoming amorously interested in some of the women warriors on Ninjato's gamechill cards.')
