No it was 75% off like it is atm. I know because I purchased it.
Voted Sim City 4 as Anno has already been on sale at 50% which isn't enough off imho. Really wish the Anno 1404 games were back on Steam, if only they sorted out that patch issue.
Anno shouldn't still be £29.99 which is why 50% isn't enough... at £19.99 or w/e 50-75% off becomes an insta buy for me
