I used to love the multiplayer focused Battlefield 1942 and Battlefield 2 back in the days. Large scale warfare, vehicles and 64 players on one map was something new and still hasn't really been done.
Good visual effects, graphics and sound; Decent story and voice acting; Hints of Sci Fi; Trademark Multiplayer.
Poor dialogues; Modern shooter cliches like for e.g; Recharging health; Short single player campaign.
