There's a reason T1 gets ignored. T2, T3 and T:S have full actor likeness rights and the works worked into the contracts and are covered under the film license for any merchandising. Anyone that wants to make a T2 Arnold product need only get the T2 license to make it look just like him if that's what they want.
T1 only covers characters and costumes, any portrait rights have to be acquired in addition from the individuals and in some cases the actor/actress may not grant it. T1 requires extra work and money, so that's why it gets passed over when an equally popular sequel is easy to deal with.
