Just finished Wario Land 1 for the first time and... it's not bad, but I didn't find it that fun either. I felt like the power up system limited you in certain ways and losing your powerup is really frustrating although that is a way to punish the player well. The bosses are also really really REALLY easy once you get the attack pattern and weakness. I loved the train levels though, they were fantastic. Now I just have to finish Virtual Boy and 2, get through 3 and buy and complete Shake it and that's all Wario Land games done.
