You have just mentioned all the adventure games ( which I have no interest in, but good luck to you if you like them) and after that, all the Star Wars shooters I already have as they came from STEAM on sale weeks.
Now go and make a list of the back catalogue stuff of EA, Activision or Ubisoft.
You would get 20 times as many games. I think Lucasarts range is very limited.
However, as I said if you like the Lucasarts adventures , go for it.
Not all of those were adventures he listed, some were 3rd person action games, while others were simulation games.
Steam only has a small amount of Lucasarts games on their site, and not all of them work that well. Dark Forces works alright, I had to find a fan mod for Dark Forces 2 in order to get it to work right, KOTOR runs weird sometimes, and Fate of Atlantis won't play in full screen. Plus, Steam only has a small portion of the Star Wars games.
I want Rebellion, Rebel Assault 1 + 2, The Tie Fighter and X-Wing games, the Indiana Jones games which aren't on Steam, and Outlaws.
Sure, Lucasarts doesn't have as many games compared to EA, Activision, or Ubisoft, but in my opinion, they have a lot more quality games.
I would love for EA and Activision to show up here, and GOG already has Ubisoft, but a lot more childhood memories are found in the Star Wars games for me.
