god-tier game; incredible game
Slang used by gamers to praise a video game as exceptionally good, often implying it is a masterpiece or life-changing.
I think this RPG is truly a god-tier game.
My friend said it was an amazing game, so I bought it.
Compound of 神 (kami, 'god') and ゲー (gē, abbreviation of ゲーム 'game'). The prefix 神- is slang for something of supreme quality.
