It does look like it will be quite an interesting game. That video they did of the sinking in real time was good although there were some inaccuracies (most minor quibbles but a few big ones like the bridge ordering hard a starboard before the lookouts have even reported in).
Another interesting incident with the Olympic happened in 1911 when the British cruiser HMS Hawke rammed into her.
It was believed that the cruiser was sucked into the Olympic by the Olympic's propellers. Incidentally Captain Smith who would later command the Titanic was in charge of the Olympic at the time.
The Titanic herself had a mishap within minutes of leaving port. Again, her propellers displaced quite a lot of water and sucked a moored liner, the SS New York, away from the docks, only narrowly avoiding a collision.
EDIT: Well Olympic was still at it in 1934:
