Are the Monkey Island reamkes worth buying? Never played the originals and only played a bit of Deponia.
If you've never played the Monkey Island games before, all I can say is buy them. Buy them now. And check out the
LucasArts Adventure Pack while you're at it.
(And be sure to take a look at the link Astral Rag posted if you want to play the first one with the much more tasteful original graphics alongside the voice acting added in the Special Edition.)
