I bought the LucasArts Classic Adventure Games pack from Steam a while ago, and I finally got around to beating the last of them (Indiana Jones and the Last Crusade).  I found that it has not aged nearly as well as the other games in the pack (Loom, the Dig, and Indiana Jones and the Fate of Atlantis).  In particular, you can easily compare it to Indiana Jones and the Fate of Atlantis, and it's not a real pretty comparison.  Graphics are worse, puzzles are more inane (a common problem in adventure games), the game is more linear, and the interface is notably more clunky.  Plus, it still contains some 20 year old copy protection that requires you to go into the game manual in order to beat the game.  Not a huge deal, but something that inhibits immersion in the game.
