DESCRIPTION:I will present sixteen galaxies from the McMaster Unbiased Gal
 axy Simulations (MUGS)\, an unbiased selection ranging in total mass from 
 5 × 10^11 M_sun to 2 × 10^12 M_sun simulated using N-body smoothed parti
 cle hydrodynamics at high resolution. The simulations include a treatment 
 of low-temperature metal cooling\, UV background radiation\, star formatio
 n and physically motivated stellar feedback. Mock images of the simulation
 s show that the simulations lie within the observed range of relations suc
 h as that between colour and magnitude and that between brightness and cir
 cular velocity (Tully–Fisher). The greatest discrepancy between the simu
 lated galaxies and observed galaxies is the high concentration of material
  at the centre of the galaxies as represented by the centrally peaked rota
 tion curves and the high bulge-to-total ratios of the simulations determin
 ed both kinematically and photometrically. This central concentration repr
 esents the excess of low angular momentum material that long has plagued m
 orphological studies of simulated galaxies.  I will discuss our recent eff
 orts to drive this material away using stellar feedback.
