I think Lurch posted about this cause I remember saying there are too many SHUMPS and GEM PUZZLERS coming out for the Dreamcast these days.
I guess if there are still people who enjoy these though, then cool for them, but as for me, I've collected enough of such games in the 90's, I've love to see a MetroidVania type title release for the Amiga and Dreamcast though.
If you like Turrican, check out Gunlord for the DC.
