Personally speaking, I do consider myself as a lapsed gamer, seeing how I was and still am an arcade-type.

Yes, I do play:

Arcade:

--タツノコ VS Capcom: Cross Generation of Heroes
--Marvel VS Capcom: Clash of Super Heroes
--Dance Dance Revolution
--GuitarFreaks & drummania
--beatmania
--pop'n music

Wii:

No More Heroes 2
Tatsunoko VS Capcom: Ultimate All-Stars
Resident Evil: The Darkside Chronicles
Wario
Arc Rise Fantasia*
Metroid: The Other M*

DS:

Luminous Arc 2
Steal Princess
Final Fantasy III
The Legend of Kage 2
DBZ: Attack of the Saiyans
Phoenix Wright: Justice for All
Megaman ZX Advent
Pokemon Heart Gold*
Golden Sun*

*Technically, they're not out yet, as of this post; I'm just waiting for their releases.

However, with this talk of "hardcore", here is my personal opinion:

To be called a "hardcore gamer" ...in America, you MUST be any of these:

--a camper
--a Zerg rusher
--or, if you play Marvel VS Capcom 2: New Age of Heroes, you MUST pick either Cable, Sentinel, Magneto, or Storm religiously.
