Well, you can go for whatever scores you like, but the object of the game is networth, not land. if i were you, i'd go ahead and set the land record since you're so close, but then i'd try to place #1 or near #1 on this list:

Dictator
--------
1. 85,100,508 NW (Round 10 - Super Size #301)
2. 56,647,873 NW (Round 11 - Peace is not an option #108)
3. 55,809,249 NW (Round 12 - Andrei Rublev #210)
3. 44,490,549 NW (Round 8 - Thunder N Storm #247)
4. 42,035,262 NW (Round 7 - Novii #159)
