Think about it for a sec... Tommy goes to prison and gets betrayed while he doesn't even know it, hates his life, gets out of prison, becomes the boss himself, becomes a kingpin, buys business', gets succesfull, loyal to friends, f*cks with his former boss, and f*cks him up bad, gets betrayed by one, loves the life, etc etc.
Michael, goes to prison at early ages, goes out. Becomes a high end criminal, robs banks, forced to BETRAY his friends, then forward, becomes deppressed and hates his life, robs again, becomes a criminal again, some what likes his life again (did he ever love his his life? Lol) and has government pressure under him, gets back to his life, quits the criminal life, becomes a Movie producer, and loves his life again afterwards.
It seems that they both are kinda same towards the end of their journey, but yeah. Is Michael De Santa an opposite of Tommy Vercetti?
