The great experimental progress in realising and studying polariton condensates has made it possible to now study experimentally a number of fundamental questions about the relation between lasing, condensation, coherence and superfluidity. In my talk, I will discuss the consequences of finite particle lifetime on several of these questions. I will discuss the relation between lasing as described by the Maxwell-Bloch equations and polariton condensation, and discuss the consequences of this for both polariton and photon condensation [1]. I will also address aspects of superfluidity [2], pattern formation [3] and coherence[3], and discuss how these are affected by the finite lifetime of polaritons. [1] J. Keeling, M. H.
