I'm reminding this just to point out that the first 5 games shown are hallmarks of people who call themselves games but aren't. These are the same people who play all the maddens and ncaa's. They're not true gamers and these titles were flashes in a pan meant to generate money, not open a world of creativity and wonder.
In the first one, Percy looks so excited. You can just hear him saying, "c'mon, let's go kick some butt". Annabeth is looking at him because she's worried that he'll leave her like all the others did and she can't go through that again. In the second picture, Percy look s more serious because he knows it's not a game anymore and Annabeth doesn't need to look at him anymore. she know's he'll be there for her.
