I'd recommend something else, since DMD doesn't really provide us with a lot to do/explore. Maybe games like Max's Life can be people's first game - it's got that standard 3DCG look about it; the game's got a lot of freeroaming; you can check in with any LI you want, whenever you want later on; there's a good guide system that lets new players know what to do; no jealousy/hard choices between LIs; good consistent animation; it's also been going on for a while. The only drawback is the MC looks like your nerdy creep, and then got beefed up to be just a scruffy hobo, and also he cums excessively.
Anything top-tier like Treasure of Nadia, Being a DIK, or City of Broken Dreamers might give people unrealistic expectations of VNs - every author out there is trying to figure it out, and it's a tough battle. Promising works get cancelled/abandoned all the time.
