Here's your litmus test: Ego the Living Planet is bobbing around in the corner of the start screen for the latest Lego game. Ego is a deeply obscure 1960s Marvel character, a giant sentient planet with a moustache. And he's in this game, if only fleetingly. That's the level of silly Silver Age nerd bait on offer here. If this news makes you grin like an idiot, then this game is for you.
