Only 9, 7 and 1 left for guessing. I'll wait until this evening for the 9th game, if it's not answered I'll have to continue.
Game #9:
Hint 1: This RTS may be too obscure, specially outside some European countries, so I'll give abundant information: It was developed by a Romanian Bulgarian (sorry, I thought it was Romanian since it included a Dacian DLC in this game) studio, that would later develop two entries in the Tropico franchise. The title of this game varies from country to country: In Spain the subtitle made reference to the Latin name of the country, in Italy to Carthage, in the UK, both to the celts and Carthage, while in the US it made reference to the Roman Empire. Those four civilizations (Iberian, Celts (or Gauls), Carthage and Romans) were playable in the game.
Hint 2: The game is set in the Punic Wars and was launched in 2003. It's the second game in its franchise, and its predecessor was set in the Gaul Wars.
Hint 3: It's an RTS, but its core mecanic depart from the usual of the genre: there's no resource gathering nor building construction, it has some RPG traits and soldiers need food to survive.
Hint 3.2: In the US, the name of this game changed drastically from its predecessor (it was similar to the UK one).
Hint 4: The developer name is Haemimont Games. This is, acording to Wikipedia, their second franchise (the first one was the RTS Tzar, that included some elements that would be further developed in this game).
Game #7:
Hint 1: Not sure if it's the longest, but this adventure is a great journey (and no, the game is not Journey).
Hint 2: Two worlds are going to collide in this Point & Click adventure: one is futuristic and tech-heavy while the other is fantastic and based on magic.
Hint 3: The game has had a sequel, but it departed from the C&P genre. It would later release a third sequel in episodic format that was partially financed via kickstarter.
Hint 4: One of the characters of this game is called Crow. He is, indeed, a crow.
Game #1:
Hint 1: I'll let you guess
Hint 2: It's a Nintendo game. Indeed, probably the "Nintendoest" game possible (and it's not an Smash Bros game).
