For me it there are two major examples of games I love but everybody hates. One for X360 "
Ninety Nine Nights" and for PS3 "
LAIR", both I recognize are not great games but well they just seem to appeal to me, N3 basically was the first major X360 release I waited for months after 360's release and even when I admit it has several flaws it mixes some RPG elements with a Dinasty Warrios gamplay that basically made me fall in love, that mix plus the availability to play different sides of story with different characters, some well developed (others not) just made the deal for me, even though most people hates it by the flaws: the bad lip sync, cheesy story and voice acting, repetitive gameplay and bland visuals.
For LAIR on PS3 it happened something similar, it is the game for which I bought the PS3, and with the prestige of Factor 5 it was a no brainer, while everybody complains about the motion dragon flight controls I found them ok , some times frustrating, but so the Resident Evil early games controls were too, plus I played the game once the patch to allow stick control and improvement on motion was released. Anyways the ability to ride a Dragon, have an on air fight with another Dragon, being able to pull a bull from the horns and throw it to a road full of soldiers and spit fire is a win for me plus the great production values of the game and 1080p.
I am sure there are others on older consoles (perhaps KI Gold on N64) but these are my more significant cases where hate is too much while I love the games.
