I'll see if I can explain it the best I can... Jesus, according to the Bible, is the Word of God. He actually created the world, and he's eternal, just like the Father. (there's the Trinity: Father, Son and Holy Spirit. All One God, but three persons... I honestly don't know how better to explain it)

Jesus wasn't the spawn of God and Mary; he's the eternal God who manifested himself as a child at one point in time. God did that for one main reason: so he could die. To understand why Jesus died is simple: we humans deserve to die because we offend God(sin). God is perfect, so He can't tolerate sin at all. BUT, God loves us so much, He doesn't want us to die. The only way to free us from hell was to sacrifice the only perfect man: Jesus. That's why Jesus came as a human, to be the substitution for our punishment. Don't worry, though. God can't be defeated by death. Jesus rose again and now lives(Easter!). We are set free from sin and receive eternal life by believing in Jesus and the forgiveness that He offers us.

Why the Son part, though(instead of uncle, cousin, mom, pet chihuahua)? Here's what I think. The Bible says we're made "in the image of God." God created relationships, sex, and, consequently, families. I suggest that families were not an originally human thing, but in fact, a God thing, part of who God actually is. Father and Son are just the best way to describe those facets of God and their relationship.

The only one I own out of those 3 is inFamous. I highly recommend it. It's just fun. If you're more into online multiplayer, though, I'd say go for MW2. inFamous definitely doesn't have multiplayer.

Okay, from last to first:

5. Commander Keen (PC)

4. Sonic 2 (Genesis)

3. Teenage Mutant Ninja Turtles (Arcade[4 player!])

2. Donkey Kong Country (SNES)

1. Duck Hunt (NES)

Commander Keen was one of my favorites growing up. If they actually brought that back, that would be cool.
