Looks fake to me. Its original old concept art was used. Everyone knows a game must have a new concept art of a character whenever they are in a new game.
This is fake. The card reads "Aaros art" in the color text in the left. The BG is all wrong to. The words CP are not fat enough and the dot in the dice is to small.
Jokes and light trolling are cool, but rolling your eyes at people who genuinely don't understand and ask innocent questions, saying "I can't believe people don't get this" and not explaining isn't particularly helpful or welcoming.
I couldn't afford a GameCube because I was paying tuition and paying for my wedding, so I know almost nothing about the original AC Games or some of the NPCs from that time. This thread makes me feel lesser for that and makes me wary of asking questions. All good, but a little kindness goes a long way.
