They don't offer it anymore because they don't want to support it anymore in case it breaks or bugs out or whatever. They need the space on servers to offer answers how to fix your games on more current games like TS3 and TS4. If TS2 was still selling as much as TS3, they might want more server space and dedicated person to fixing problems in the games (I mean crashes, tech stuff etc.) but since TS3 still sells as much as TS4 packs, sometimes, then I guess they need to have customer support work on any tech crashes and the canned responses of how to fix those things in TS3 rather than waste money on telling people how to do those canned responses for TS2.
