You can count me in on the Blitzball lovers circle. Played it for hours and had lots of fun with it. And yep, Tidus + Jecht Shot was key but by that point I had other scorers and didn't always need Tidus to make goals. I even liked the "coaches only" version in X-2.
I haven't actually finished X-2 but I will over the Christmas break for sure.
As for the "imprinting" theory - it may be true in my case. My first FF experience was with II (Japan IV) and I really enjoyed it. More than III (Japan VI). VII was such a different experience that it's hard to lump it in with the 16-bit games. I've played V but I didn't play it long enough to get a solid feel. One of these days I'll try it again
I got to Disc 3 on VIII and gave up because I wasn't having fun. Game was plodding along, the combat system was bleh and I really disliked not being able to feel powerful by leveling up for a few hours like in just about every other RPG. That's fun sometimes and the scaling battles of VIII were just annoying at the time. The most fun I had was actually with the card mini-game.
Never played IX.
I had pretty much given up on the series after VIII annoyed me so much. I didn't pay attention to all the hype surrounding X. I figured it would be too much like VIII. For some reason, probably because I needed something to play on my PS2 I picked it up. It quickly drew me in and I ended up really liking it. I took a break for over 10 months on the road to beating it but that was okay. I just read a walkthrough up to the point were I was at to get the story back and I was all set.
I liked it so much that I got all the weapons and did almost all the side quests (gave up on the monster one because I wanted to see the ending). When they announced FF-X2 I was on board from the start. I had no problem with the focus on girl-power and the cheeze factor. C'mon - everything is better with cheeze, right?
FF-X2: I did miss the sphere-grid system from X but I ended up not minding and eventually warming up to the Dress Sphere system. The story took a little while to get pumping but I was so pleased to get a real sequel to a FF game that I really didn't care. I've missed some items along the way and botched some of the chapters but I'll probably end up playing it again as it was pretty much designed for multiple play-throughs.
The end of combat banter of FFX/X-2 was great. The fighting (especially in X-2) was smooth and fast which was really what kept me playing initially. I can't stand games anymore where the combat takes forever.
So the short of it is that I'm back on the FF wagon. I enjoyed FF XI for what it was. Played it free for a few months then gave it up - got a free HD out of it. All good.
I'm looking forward to the re-releases of IV & VI on the GBA to play the old games again. I still have them for the SNES but that would mean hooking up *another* game system to my already cluttered media center. I imagine they would hold up well...
