Illbleed. Before everyone and their brother decided it was rare and worth money and Supergreatfriend made it an internet sensation. Same with Rule of Rose. I thought both were terrible games when they were new. Let's not even talk about my initial reaction to Seaman and Mr. Mosquito. I played Ghost Lion, Athena, Chulip, Siren, and Krion Conquest too. The problem with most of my 'obscure' gaming experiences is that the moment game collecting and youtube Let's Plays became a thing - suddenly these crap and/or obscure poor selling titles became gold to hipsters and better known.
