The Gold Box D&D games are coming to Steam

pcgamer.com:

The Gold Box games are legendary among RPG fans of a certain age. Published by SSI through the late '80s and early '90s, they're based on numerous classic D&D settings including Forgotten Realms, Dragonlance, Dark Sun, and Ravenloft. They're a seminal old-school RPG experience, and later this month they'll finally be available on Steam.

The Gold Box games will be part of eight separate collections:

The Steam editions are being remastered by SNEG, a small publisher founded by former GOG employees that focuses on remastering and re-releasing old games. They'll feature a number of enhancements including a special Gold Box launcher that will simplify the process of managing the games and moving parties between them, enhanced DOSBox support, and various companion apps.

These collections are already available on GOG, and it's not clear how, or if, the Steam releases will be meaningfully different. The GOG versions don't include the auto-mapping apps, for instance, but that's not a big deal because they're freely available for download; they do include hint books, which the Steam pages don't mention—but the Steam listings also don't mention the instruction manuals and believe me, you're pretty well hosed without those, so it's reasonable to assume they'll be included.

I've reached out to SNEG to ask about the differences between the Steam and GOG releases, and will update if I receive a reply. In the meantime, some personal advice: The actual Gold Box games are extremely old, and unless you know you want to play them, you probably don't. Eye of the Beholder 2: Legend of Darkmoon, on the other hand, remains an extremely playable, and extremely good, dungeon crawler.
