Quoted from Sinestro:Cleland's voice mod is an easy fix if you don't like the voice actors.
I sold SM and bought GOTG and don't regret that move for a second. SM is a great pin, I wouldn't mind owning a SMVE at some point, because the art in the original is just bad. IMO SM just feels chopping wood. The new code for GOTG has improved the game tremendously with .87+, the modes are unique and fun, the video, callouts and music integration with cleland sound mod is awesome.
I agree the bad voice actors are a little annoying. Here is the mod thread...fix it. https://pinside.com/pinball/forum/topic/gotg-sound-replacment-mod
