Rear-view mod is good for DMs, cromedome's filler packs add a lot of helpful bricks, Tier and Tactical (T+T) weapons (don't flame me. It is a commonly used addon, and having it would reduce other server load time), Too Many Bricks Inventory (TMBI) gives you more brick inventory rows, Trueno's (original) colorsets (are widely used and very well organized colorsets), Filipe's and Phydeo(u?)x's vehicles are widely used and well made, VCE(extremely helpful for advanced eventing if/when you get there).
