Honestly my guess would be as good as anybody's... well maybe not anybody's, seeing that there are a lot of idiots on this board, but you know what I mean. If Pac would've never been dumped on in Vegas (as if he never went), this is what I think would've happened, if Pac had his way after Makaveli:
* VHS release of the All Eyez on Me music videos (with all the videos we know about, plus the three-verse solo version of All About U and videos for Ambitionz Az a Ridah and All Eyez on Me since he had interested in making them)
* Completion of the Made Niggaz short film
* Release of Gridlock'd soundtrack(s) as he intended: one with one or two Death Row artists and some alternative rock songs (some of which were used in the actual movie), and one with all hip-hop artists, mostly Death Row
* Official launch of Makaveli Records (a subsidiary of Euphanasia), possibly still connected to Death Row
* Start of Klockwork Productions (with Johnny J) and 24/7 (with Tracy)
* Completion of One Nation album and virtual end of any East/West beef as a whole, even though he would definitely still have problems with Bad Boy, Mobb Deep, etc.
* Completion of Outlawz album (with Fatal) and release under Makaveli Records
* Release of Pac's reply to Mobb Deep's "Drop a Gem on 'Em" and underground Chino XL freestyles as B-sides to One Nation singles or Outlawz singles
* Release of Pac's "all clean, all positive" album
* Opening and funding of several community centers (since Pac wanted to do that, plus he said that everytime Makaveli went platinum, he would donate money)
* Filming of Baby Boy (since I remember hearing that Pac was originally supposed to play the lead role, then Singleton stashed it until he met Tyrese)
* Conceptualization of Live 2 Tell
* Increased involvement as a political figure; not necessarily with a position (mayor, governor, etc.) but as a well-known activist
* Completely matured, unbelievable Pac style involving his political side (as seen in his 2Pacalyse Now lyrics) with his improved lyricism seen on Makaveli and beyond (especially on "First 2 Bomb")
I'm getting a headache at this point, there is just so much stuff that Pac was going to do. Oh yeah, you need to factor in some confrontation with the New York guys he dissed on "Against All Odds" (King Tut, Hatian Jack, Jimmy Henchmen). Tut at least would've wanted to send Pac a "message" all the way from the East Coast for that line.
