Yeah, T2: The Arcade Game is a great game... I loved it in the arcades back in the '90s, and have, and like, the SNES version as well. It's probably better than the Genesis one because it supports the mouse, not only the Super Scope... unless the Genesis version has Mega Mouse support? Mouse is great for lightgun games. It makes them a bit easy, but I'm terrible with actual lightguns, so that's not too bad.
^yeah, as i recall that game was pretty much THE reason to have a menacer; like, both it & the super scope had pack-in mini-games (though ours at least brought a ToeJam & Earl one! yeah, none of them were great), im trying to think of a SS game that nearly justified its existence as much as T2 did for sega at the time, me & my friends would play the crap out of that one. it was cool trying to shoot up the robots till this circuit would pop out of them, i recall it being mad points or something if you could hit it in time
Well, T2 and the 6-in-1 cart that came with it were literally the only Genesis cart games that support the Menacer. Sega had made a whole bunch of lightgun games on the Master System, and did some great ones on Saturn and Dreamcast, but somehow the Genesis didn't have any apart from the 6-in-1, first party wise. Very odd. I mean, in design the Menacer is an obvious Super Scope knockoff, but given Sega's long history of lightgun games both before and after the Genesis, it's strange that they didn't really make any (that one super shoddy 6-in-1 aside) that generation, on consoles at least.
The only other games that support the Menacer are American Laser Games' stuff for the Sega CD (Mad Dog McCree, etc.). They support both the Menacer and ALG's own Sega CD gun. I'm not 100% sure if the ALG gun works with those two Menacer cart games...
