There is so many things to do in GTA III, so let's come with 2000 things to do.
1. Don't repeat the same point.
2. All points must go in order. Do not go off the track.
3. Don't say the point that's possible to do only with the cheats or trainers.
4. Don't say something that's impossible to do (example: Force Claude to swim).
So let's start!
1. Complete the first mission (Give me Liberty / Luigi's girls).
2. Drive a car around Liberty City.
3. Complete a game without getting busted.
4. Complete a game without getting wasted.
5. Fly a Dodo more than 300 seconds.
6. Get busted.
8. Complete 4 Off-road missions.
9. Get 100 Hidden Packages before Don't Spank ma Bitch up.
10. Kill 100 peoples in 3 minutes.
So the next person who wants to quote points to do should begin with 11, 12, 13 etc.
