There's nothing particularly wrong with Shining Soul II on the GBA - it's rather like PSO in aspects I find, and would be even more so if you could play it online.
I think the frustration stems not so much from the fact that the new Shining games aren't as good as the old ones, and more from the fact they're more action than strategy-oriented - we Shining fans know what we like, and that's grid-based, turns-based battle systems.
Sega have themselves said it's unlikely they'll make another strategic Shining game, so this seems like the perfect chance to resurrect the best SF fangame ever

Even so, the new games still aren't getting much attention from the press.
If I had the time I'd probably get one just to try it out.
At least the press seem to be giving the new ones the benifit of the doubt; there's one in 3D coming now, maybe that will get it some more attention from the media?
