At their fundemental core, yes, megaman games play alike. However every megaman series does things differently than the others. The Mega Man series plays differently than the X, Zero, Legends and Battle Network series. Megan Man and Mega Man and Bass are both part of the original series thus they share a lot of similarites. X is most similar to the original series but Mega Man is all around more powerful + agile and everything is built to reflect that. Legend is a 3D adventure series. Zero is harder, faster, mission based 2D action and has plenty more customization. Battle Network is an action rpg. SO if you're still interested in Mega Man but find classic to stlae, try one of the other series.
