IV, V and VI I all played around the same time which I believe was about 4 years ago.

VII... well technically a few weeks ago when I made the Pacifist Dyne video, but as for a full playthrough, it's been a while. A little before the NT mod's release I believe, that would make it about 3 years.

VIII, when it came out on Steam.

IX about 5 years ago.

X I started a game on when it came out on Steam, full playthrough was when the HD Remaster first came out. X-2 same as X.

XII I refought the Judges a couple months back, but my last full game was when we got ourselves a copy of IZJS, which was 2 years ago I think.

XIII and XIII-2 I only played when they came out and never again thereafter. LR I also started a game when it came out, stopped after about an hour or two though.
