Is there even enough variance in the Space Invaders series to warrant a collection?
As someone who only ever played the first one, this feels like if Microsoft released Minesweeper Collection featuring hits like Minesweeper 3.1, Minesweeper 95, Minesweeper ME, etc.
My friends and I would pass around the Days of Memories games as we hung out but the only ending we ever got was the Kula one, where the climax has you being interrogated by whom I assume is her over-protective brother K’ and you have to tell him the correct input commands for Kula’s super moves to show just how much you care about her.
