I've only played the IM demo, but I love the parts where he swings with his whip across lava. That is just Indy to me. And the theme plays at the same time. Yeah, Indy all the way.
my defining moment was when i got run over by von becks digger tank for the fiftieth time-i realised how hopeless and pointless life is without quicksaves :-) naw jk, i liked the parts when you gave an uppercut to some nazis chin, defeating him, and the victory music plays...so very cool.
Indy getting spooked by a cat "statue" while rummaging through the university's storage rooms in FOA, and then falling down a chute... oh yeah... that's Indy. Or not.
I'm with Indycrusader. I remember the first time I played the IM demo. Swinging across the lava (then running from the boulder) with the 'Raiders March' playing just seemed so perfectly 'Indy' to me.
(My PC is too old for ET and they haven't released it for Game Cube so I haven't tried that one yet.)
