I've got D2 + Expansion, as well as Warcraft 3 + Expansion.
Even played some WC3 LAN matches with sister after 10 years, bring back memories.
But since I've assembled a newer PC lately... I've starter running newer game.... Like Trackmania United for example.
Or Shootmania Obstacle, which is an FPS game with a mode dedicated to movement mechanics... simplistic, but just the way I like it.
Cuphead is also very enjoyable and FarCry Primal at times.
