@sean Beneath a Steel Sky, and Indiana Jones 4. I believe the former might be free on GOG?
@sean Absolutely magical when I played it in the '90s. Got completely sucked into that atmosphere. Not many games managed to give me that feeling.
Near the end of Primordia came close. Some bits of Syberia came close. Indiana Jones 4 definitely came close overall, I've replayed that one at least 5 times I think, because it's a really grand epic adventure.
