Here's a hypothetical situation. Imagine that the original game is represented in a ball form. Now, the ball can bounce around, roll, be still, entertain, etc, but, no matter what you do, the ball stays together because the ball is cohesive. Now, as time goes on, the ball may be seen to be less fun to play with because it lacks things other newer forms of entertainment possess. Reasonably speaking, releasing the next version of this ball should probably just bring the ball up to date so that it can compete for attention well against other entertainment products: new packaging, refurbishing old parts so that they thrive in modern environments, and re-advertising the product (harkening back to what made it great at what it did previously).
Enter War of the Lions
. Instead of (just) bringing the old game up to date, they made something akin to a lava lamp, tossing an old game in to drift aimlessly around for the rest of forever amidst the newer, brightly-colored lava lamp goop and to bang into the smaller representations of other games also dumped into said goop. Can lava lamps be entertaining? Sure, but are they a cohesive mixture anymore? No, and so my personal dislike comes from the fact that I don't see FFT:WotL as a cohesive game. I see it as "game-ish"; there's a cohesive game somewhere in there (sometimes it even rises to the forefront) but it's lost amongst other things.
If you were to order a smoothie
and that "smoothie" was just unblended fruit in an attractive cup, would you like the product as a smoothie?
