Well, for now I can tell you that you shouldn't have opened new topic, just revive old one (which is not that old mind you). I got interested for this game in first topic, but I have run out of ideas... Any clue when have you played the game? Is it from mid 80es or perhaps newer with retro graphics? And you're sure it is PC?
Check
Cold Dreams and
Atlantis for some Greek feel to it, but no cemeteries. Also check
Stormlord and
Risky Woods... At least those games are good so you can have fun before discovering it... You sure it was DOS game again?
