:::Yeah, I saw that too.  I wasn't really looking to make a list, per se, but made mention of a couple, including Alien Soldier, which I used an image for.  The thing is, though, they're not "Sega Channel" exclusives - they're regional exclusives.  Unlike Meganet, Sega Channel's releases were all launched on cartridge, but some weren't released in North America but were on the NA Sega Channel, like Wily Wars and Pulseman.  It's also worth noting Sega Channel wasn't a North American exclusive service; even Sega's official website, in an archive, said as much.
