For multiplatform games, should we write only the console we played it on, or all which were available day 1 / similar ports?
Like Lego Star Wars: The Complete Saga (Wii) which was completely similar to the PS2/Xbox versions, and
Resident Evil 4 (GCN/Wii) since it has completely new controls and released long after, yet I have only played it on the Wii?
Yep.
