Summary: If you enjoyed Lego Star Wars, Batman, and the original Indiana Jones game on the PSP, but were disappointed by Indy 2, be warned that this a further step downwards for the PSP Lego franchise. Where the original 3 Lego games were great ports of console games, this appears to be a sad port of a DS game, and not up to the quality you would expect for the PSP. In this one the gameplay is glitchy and boring, as anything resembling a challenge has been removed.
Summary: Unfortunately as with Lego Indy 2 this is a port of the DS game rather than of the PS3 game. (Star Wars, Batman, the Original Indy are all absolutely superb as they match the console versions). I won't be buying any more of the Lego games on anything other than the xBox now as they are a waste of money.
