for example
Star wars battlfront 1 and 2, i didnt like the way sw bf2 was set up, and how some of the planets where changed where annoying because you where used to the first ones (geonosis) the space battles where alright but a bit of a bore after a while just doing the same stuff over and over, limited decent playing ground planets, didnt like how the ammount of people allowed in the ships changed (republic gunship allowed 6 people in bf1 and then 4 in bf2) the planets in bf1 where great and i could play them over and over, bf2 should have been set up as bf1
