A few years ago, Sierra/Activision brought collections of multiple games to Steam, such as Space Quest and King’s Quest, but skipped over Leisure Suit Larry.
That finally changes today with Assemble Entertainment publishing Leisure Suit Larry games from one through seven (Lost Floppies not withstanding) as well as Magna Cum Laude. Each can be bought separately or in a bundle which is currently discounted to $21.35.
Serious deal hunters may instead want to grab the games on GOG, where they have been available for a good long while already. During the GOG sale the same batch of games can be had for $16.98.
