[PC] UPlay - Discovery Tour by Assassin's Creed: Ancient Greece - $7.49 (RRP: $29.95 AUD) - UPlay Store

I am a bit unsure which category to pick for this as it is not a game per se but still uses a gaming service to be activated on and is closely linked to a game which means gamers are most likely to recognise this.
Maybe the mods can add an extra category for "education" for this deal.

So, this is NOT the game but instead something like an educational holiday via PC but you do not only go to a different place (Greece) but also a different time (ancient).

From the website:
