Do i need BFME 1 to play BFME 2?

No, you do not need "Battle for Middle-earth 1" (BFME 1) to play "Battle for Middle-earth 2" (BFME 2). The two games are separate titles, and BFME 2 features its own storyline, gameplay mechanics, and factions. However, owning BFME 1 might enhance your understanding of the lore and setting, but it is not a requirement for playing BFME 2.
