The Jane's Simulations, " Ah-64 Longbow" in particular. Best Combat Helicopter sim ever.
American McGee's Alice.
Weird thing is EA released a version tweaked to run on modern computers as a bonus for "Alice Madness Returns" but never released it as a separate purchase.
Alice:Madness Returns was a big disappointment, though.

The LOTR games you will never get because of licencing issues; EA lost the licence to Warners Interactive; EA no longer has the rights to sell them.

GOG being caught up and having parity with what they've released over on Steam would be ideal. I've been wanting to replay the Mass Effect games for some time now, so having the first 2 games released over here would be nice.

Sadly the rights to the Jane's moniker is held by IHS Markit Ltd., as the Jane's Information Group is one of their subsidiaries. Two Jane's games made by Sonalysts Inc. did get out, but separated from both EA and the Jane's Combat Simulations prefix (688(I) Hunter Killer and Fleet Command, both on Steam).
