Though not as popular as Final Fantasy, Dragon Quest, or the Chrono series, it is still making a profit. And as long as it makes a profit, new ones will be made. If you don’t believe me, ask yourself one question: How many Mega Man games are out right now?
Uh...When was the last Chrono game out, hm? Megaman games are just easy to pump out because they mostly follow the same basic pattern...And they still manage to keep that same basic, fun, easy-going gameplay. Much the same can be said w/other popular franchises: Mario, Zelda, Metroid, etc. RPGs, on the whole, are on their own...
