I'm sort of in two minds about the direction in which SE is going. To me, FF13 and Versus sound like they're going to be quite good (Agito not so much), and the recent remakes of the older titles in the series are good because it makes them more accessible to the general public, which is a good business move for SE IMO.
I have no objection to SE working on three titles at once. Squaresoft began production on FFVIII and IX at the same time, and they both turned out to be great games. Nowadays Square Enix is much larger and has more resources so producing three games should work out just fine.
What I don't like are all these "extra" games and unnecessary sequels/prequels, namely, the Compilation of FF7. I shouldn't really judge before I play some of the games, though, but for now I just pretend they don't exist. I mean, no-ones forcing me to play them.
Also, I didn't really appreciate how they got rid of the world map system in X, and I don't like FFXII's battle system all that much, but I'm glad SE's pushing the boundaries and experimenting with new things, and IMO those two games were still awesome despite not being the "typical" FF.
So I guess all-in-all I'm quite happy with the way SE is taking FF. (Say "No!" to the FF7 Compilation!!)
