I looked for some of the games you say can be found on DLsite, but I can't find them, or what I did find has a different title.

The titles are a bit different than the way DLsite's English site lists them. This is because they like to "translate" the title instead of presenting it in Romaji the way we do, so there will be a difference. We can't change the way they do things over there since it's none of our business, but we have reviewed a lot of games there that also get a mention on this site, and provide links directly to the game featured on DLsite in our reviews. If you're interested in the game, we'd like to encourage you to buy it!
