This game suffered from a lot of hype and bad marketing. Promising so much, and yet giving all the players, that waited for it years and years, so little, it quickly lost all the attention and publicity it got over the years.
I'm talking about Messiah, a game that luckily is available on GoG.com (

Made by Shiny entertainment, and distributed by big old Interplay, this game caught the attention of the media by the excellent graphics, and a simple quirk in its gameplay, being able to possess any NPC you wanted, as long as you needed.
A hybrid between an adventure and a horrible third person shooter, this game told the story of the angel Bob, brought down to earth by God to cleanse humanity from all its sins, in a futuristic and cyberpunk atmosphere.
I played the hell out of this game when it came out, and I endured the horrible puzzles, the subpar shooting sections, all because the love I've grown for this game across the years.
It is not quite forgotten, but people overlook it fairly easily.
Seven Kingdoms: Ancient Adversaries (1997)
Not too obscure, but often overlooked. It's one of the best RTS ever. There was a sequel which is supposedly good too, but I never played it.
The sequel is fine, but truly is more of the same. There a lot of new mechanics (controling the monsters as a faction or some upgrades to spionage, for example), but is all cluttered and quite annoying. It looks like a enormous game, but soon you realize it is quite empty and it even feels rushed, perhaps by all the competition of the time. The first is one of the best RTS I played in my life. Even so, if you loved the original, you will enjoy the sequel.
