The way we do astronomy has changed dramatically over recent decades. Numerical simulation has become an important pillar. While new observations pose new challenges, simulations are able to answer many of the key questions regarding galaxy formation, which were unimaginable just half a couple of decades ago. I present the arrival of a new galaxy cluster simulation, "NewCluster," which is a state-of-the-art simulation in terms of spatial (68 pc), mass (2e4 Msun), and time (15 Myr) resolutions. Thanks to the superb resolutions and up-to-date input from astrophysical prescriptions, we can effectively investigate the origins of many key questions, such as the massive galaxies at high redshifts, black hole-galaxy mass relation, AGN feedback effects, dust formation/destruction, low surface brightness galaxies, and intracluster light. The cluster is currently experiencing a merger at z~0.6 which is expected to be completed by z~0.4. We present the prospective use of this unique simulation to study galaxy evolution in greater detail than ever before.
