LucasArts is a computer game company founded by George Lucas. Before becoming a separate entity, the games were released under the Lucasfilm Games label.
While building its reputation as a developer of excellent graphic adventure games beginning in the late 1980s, the company switched to marketing the Star Wars franchise in the late 1990s. It is doubtful LucasArts will produce any more adventure games.
LucasArts produced many adventures like the Monkey Island series based on the SPUTM engine, which used the SCUMM scripting language, which also gave ScummVM its name.
The last two LucasArts adventures Grim Fandango and Escape from Monkey Island, being 3D Adventures, did not use the SCUMM scripting language. However, at least for Grim, there is ResidualVM.
PASSIGAR also has a very good list of almost all known LucasArts game versions
