both correct!

I played through HoMM2 again in the past year.  I now realize what I like so much about it.  It's the main campaign.  They did an awesome job on both the good and evil path in the main campaign.  I enjoy playing the expansion campaigns too, but they are not nearly as good as the main campaign.

I say this because, I think HoMM3 really does have better mechanics overall.  However, I like the main campaign so much in HoMM2, that I end up preferring that game, even though both are very good.

Nope.  Mnementh already got it.

Both 12 and 9 sound like Kingdom Hearts to me.

Yoshi's Island? Not sure if people may think of it as a spin off or a part of the main series, but I'm throwing it out there.

Well, not correct for either one, but don't disregard it completely.

More hints:

#8:

• Greater understanding of the world allows for the truth to be revealed.
• Dream, or a nightmare. Maybe both.
• At the end, will you accept the offer to wake up, refuse and take up the mantle, or defy even the nightmare itself?
• Blood of the old ones.

#7:

• The English script for this game is longer than the entire Lord of the Rings-trilogy (455,125 words) by over 260,000 words.
• Picks up immediately after the first game, after a surprise reveal at the end of the first game leading one of the two main characters to leave and disappear.
• A proper Bracer now.
• Ouroboros

#6:

• To revive, you must kill.
• An abandoned, forbidden land.
• 16
• As you complete your tasks one by one, the corruption begins to change your appearance.

Shadow of Collossus

Correct.

Nope.

8.  Dark Souls 2

7.  Trails of Cold Steel 2

No. They were both on my list earlier, and you are somewhat close, but neither is correct.

Guessed by Darashiva

'MediEvil' has just the right kind of whimsical, lighthearted story and humour I'm looking for in a video game. It also has a fantasy medieval setting, which is always nice, obviously to make the pun of the game's name. It is a level-based adventure game, where you can play some out of order, some have to be visited multiple times and some are optional. They are all selectable on a nicely decorated map that shows miniature versions of the layout of the levels imbedded in a landscape. I like detail like that. The "Kingdom of Gallowmere". The level design is very varied, and I particularly look back fondly on two of them.

One is a level that is completed by solving various riddles. A statue tells you a riddle, and you have to figure out what to do at some point in the level to open up a new path, and a new riddle. The other is an insane level that is an onslaught of hundreds of enemies in an insane asylum. This level is actually not easy, even though nearly all the enemies are one hit kills, you'll get overwhelmed at some point. The whimsicalness and humour lasts right up to the end culminating in a particularly original final boss fight. And because you don't want to miss all this, you remain hooked until the end.

New day, new game, new hints.

#9: The final game in this franchise that included a number in its name.

Hint 2: At least this time it's just the actual number and not one with a few zeroes added to it.

#8: Halfway through one part right after you jump you can turn right and visit a location from another game.
