Hi, I'm completely new to these forums and haven't had time to read through and see if this topic was made already (tell me if it exists), but here it goes.
Yesterday I decided to install Far Cry again just for fun (Far Cry 1 that is). You all probably know that the main character, played by you, is called Jack Carver. When I saw him in the first cinematic, it instantly reminded me of The Jackal in Far Cry 2.
It's probably not true, and Ubisoft didn't think about it, but there is a possibility.
The Jackal wears a red Hawaii-shirt (if I remember correctly), same does Jack Carver. You might think he should've changed his shirt since the first game, but who cares?
They have the same hair-color, same hair-cut, although not the same voice. Maybe he ate too much African food and changed his voice, who knows?
Another reference which is just a coincidence is the names. Jack Carver. The Jackal. JACKal. A coincidence probably, but still funny.
The Jackal also speaks about being a "dirty mercenary" in one of the clips where you meet him (in the hut where you get the diamonds if I remember correctly), and Jack Carver was a mercenary from what I know.
This is probably all just coincidences, and nothing that Ubisoft thought of. But if it isn't, it might be the only connection that Far Cry 2 has with Far Cry 1.
