Honestly, lots of maps need a remake. Valve is really far behind now. Sure, CS isn't a AAA graphics type of game but it looks really outdated now. Even in the official map pool mirage, overpass and train all look really old. Office is really popular and look outdated too. But there are a ton of other hostages, arms race and so on... maps that are all outdated now. Those maps might not get that much play but they are still part of the game and they can't ignore it forever.
