I suspect you'd think Contra III and Super Metroid are more similar than Super Metroid and Castlevania IV too, because you use guns in two out of the three.
But I digress, I can't discuss something with somebody who doesn't even address more than one of the points I made.
No they are not and your points are not good ones so heh no point. You made surface level comparisons. Yeah maps and lore. Still play like totally different games.
