Yeah the Wii version also had the bonus coop story to play as Henry Sr alongside Indy!
I can't decide whether I like the PSP or PS2 versions but the PSP one is for sure has better game mechanics.
I wasn't a fan of the ps2 version compared to the Wii version.
-Loading times are much longer
-Framerate is 30 while in wii it's 60
-Graphics are worse and in the first level the airplane doesn't have any shadows !
-No coop mode and versus mode.
-Less Whip grabbing moves compared to Wii version.
-Shooting sections having inferior controls compared to Wii version.
The only part of the Wii version I didn't like was the "shake the controls to make Indy run " sections that were much inferior to "mash buttons to run" sections in the PS2 version.
But I still prefer the PSP version since that has a better ending and better story imo.(alongside kinda better controls outside of those shooting sections)
