I was tired of finding my CD for HOMM2, so I've waited for months for it to show up on GOG -- I think I'll be playing HOMM forever, and I look forward to finally finishing it with the GOG copy.
This is a turn-based game that is a huge jump from HOMM1 and set the standard for all the HOMM games to come, and which was perhaps never surpassed by other strategy franchises.
