Judging from what I've heard, The Force Awakens sounds like a future reboot of Star Wars. Let's see what's similar between Episode VII and A New Hope:
Protagonist comes from desert planet, check.
Villains have planet destroying (or star system destroying) superweapon, check.
Said villains use said weapon to destroy a planet in order to intimidate the galaxy, check.
Superweapon looks like a planet, check.
Said superweapon is destroyed by X-Wings, check.
Old guy dies, check.
Antagonist is somehow related to the heroes, check.
Superweapon tries to destroy good guys' base and fails, check.
Is there any other similarities that I've missed?
