Heroes Of Might & Magic III
- The third game is widely considered the best in the series, and with a steam community the multi-player could be revived.
Grand Theft Auto London
- Considering Steam has almost the entire collection including the first, why not this game? It's a classic!
Broken Sword IV: The Angel of Death
- With 5 coming fairly soon, and the previous 3 games being available on the service, 4 should be a no-brainer.
Monkey Island & Grim Fandango
- The LucasArts selection on Steam is very underwhelming. These games are LucasArts best, and so should be there!
World of Warcraft & Guild Wars 2
- As I play both of these games, I would love to see them added on the service. It would make communication with other players much easier. Sure, you can add non-steam games to your library but to be able to track stats, plus the all-round accessibility and community are features worth having.
LBA 2: Twinsen's Odyssey
- Much like Grim Fandango, LBA2 is an adventure title that never really made its mark on the industry, despite having the quality of a legend of zelda game and the kind of charm never seen before. Being available on steam, particularly during sales would guarantee a lot of sales to a demography yet untapped.
