Ultimately the problem with Lego Indiana Jones 2: The Adventure Continues is that it just isn't as good as its predecessor. It was a formula that would be pretty easy to repeat, but surprisingly Traveller's Tale has overcomplicated things which isolate it from a key part of its intended audience: children.
When you bear in mind the predecessor is relatively inexpensive to pick up now, it just seems pointless to recommend the newer of the two. If you want a family game to keep the kids busy this winter, go with Lego Indiana Jones, it's fun for all the family. This game just gets far too irritating to be worth a look.
