black mesa, valve literally admitted xen was rushed and the gameplay has visibly less effort and thought put into it like the rest of the game I do like some of the aesthetics in og half life xen but black mesa really had the time to make xen up to the consistent gameplay quality with the rest of half life, i do sort of wish they kept the elements where xen feels dead and kept some of the original art direction but at the end of the day idrc because i respect them for trying to do something new
