I seem to have struck a nerve.
I didn't try to suggest that sandboxes are better games. That WOULD be dumb, which is why I didn't do it.
I've done an extensive comparison of FFX and FF13 and how they are fundamentally both very linear games, but X feels like an exploration whereas XIII feels like a corridor. You can have a linear experience that is crafted to feel like exploration and it is fantastic. See portal, half-life, earlier FF games etc.
No one can convince me that the linearity in XIII was the good kind of crafted linearity, it's painfully obvious it was thrown together (see below).
Fair-enough, but we like some degree of control. Even FF12 let you specifically choose how your auto-battle acted through gambits, and for that matter how your non-controlled allies acted.
FFX is a game hampered by translation.
FFXIII is a game hampered by having no director for most of it's development. Have you ever noticed that the plot is basically short conversations at the start and end of every area, with nothing to do with the area they are in? It's because the dev team were just instructed to make tons of beautiful levels (which they did admirably) and they just connected them end on end and threw a plot at it.
It's pretty well documented, just google it. It's also the reason FFXIII-2 exists. They made too many levels and didn't want to waste them. Not kidding.
You're probably right, but standards are higher now so it's fairly irrelevant.
