For me it was Get Bass! (Sega Bass Fishing). I played the import Japanese game at an Electronics Boutique in March of '99 while they were trying to build hype for the fall. The pacing, graphics, and ease of gameplay sold me then and there.

Knowing it was the next Sega system, i kept an eye out for the announcement of Virtual On, and when it was.. I never looked back.

In the USA, Sega Bass Fishing did not come out till late Sept '99, while we had the system in early Sept. So at launch I got the beloved arcade port, Hydro Thunder. I knew nothing of the NAOMI Board conversions and what-not. I was pleasantly surprised at how many Sega games could just "come over" from arcade to TV... ah... "those were the days".

ANyone else drawn in by a specific title, or a few titles? Was it a launch title, or a future title?
