Who has the better platformer games? Sonic or Mario? It depends on whether you prefer running action or jumping action, I think. I lean toward Mario, because I've long felt -- and seen -- that there are more possible gameplay variations with jumping mechanics than with running ones.
Now we've got a Sonic role-playing game to match against the Mario ones. I've been playing "Sonc Chronicles" on the DS the last few days. What it borrows from the other "Sonic" games are the diverse character abilities of Sonic's wide case of protagonists. It doesn't, however, do much with the core element of "Sonic" platformers: speed.
The "Mario" role-playing games -- ranging from "Paper Mario" to "Mario & Luigi: Partners In Time" -- aren't able to take advantage of as well-defined a set of gameplay character traits as the Sonic RPG. It's not like Mario should have obviously different abilities from Luigi, the way Sonic should from, say, Knuckles.
What the Mario RPGs do borrow from their platformer source material, however, is a style of action-first and ease-of-use. They translate their style of platform gameplay better than the Sonic RPG appears to. The Mario RPGs tend to be more streamlined than the average "Final Fantasy," giving players fewer items, fewer side-missions. And, most prominently, the Mario RPGs have usually included a lot of reflex-based gameplay. In some of them, you can even play them like Mario platformers, jumping on the heads of enemies and defeating them without even going into turn-based battles, if you're powerful enough.
The Mario RPGs feel more "Mario"-esque to me than the Sonic RPG feels like a "Sonic" game. But I do appreciate the "Sonic" RPG's successful use of a diverse set of characters, something the Mario games haven't ever managed that well. Gaming's two most famous mascots have found a new realm in which to be compared. I think they'll be richer for it.
Next: Over the weekend, I'm trying to play much more of "Lego Batman" and I'm finally starting my final copy of "Fracture." I hope I like it as much as I did the preview builds.
