I thought it was a pain in the ass. It's better than the ability system in FF13 though, at least in 10 you had a choice of where to go.
It was such an awful experience for me. Maybe I just sucked at it. But hey, that's great you had fun with it. Whatever floats your boat.
I noticed it immediately.
You just described the problem that arises without an explorable map. Without a map to explore, you ARE only restricted to towns, dungeons, and points of interest. You can't see the entire world, you have to go where the game takes you. And with the case of FF10, once you get the airship, you could select where to fly. But again, you could only choose from towns, dungeons, or points of interest.
A world map like in previous FF's provides a way to explore and see the entire world. I get that you can only enter specific areas, but it certainly gives you greater freedom of exploration. Something that I feel to be important. That was my problem with 10 and later, you couldn't actually see the whole map, only specific areas important to the plot. It makes me feel closed off and restricted, I didn't like it. I missed the ability to go off looking for an obscure town, or hut, or cave, or whatever. I think it makes for better secrets.
All my opinion, of course. No doubt you think differently. I do agree that giant characters running around looks silly, but it wasn't a problem for me.
By the way, I still think FF 10 is a good game.
