Even though it seems that games have been around for ages we are really still at the beginning I imagine. Doom, Half Life - well you could come up with a long list.
I would hope that games like AGEOD make as well as the mainstream could still be remembered, played or studied in years to come.
One could even make a case that some are works of art.
Just a thought after sitting in the garden nursing a beer or two
