Comparison with 1830

1. Same full capitalization, much larger scale
1870 uses the same full capitalization system as 1830 and shares the same bank size ($12,000), but does so on a huge map west of the Mississippi, designed so that nearly every company that manages to float can end up being profitable, instead of the more competitive, resource-constrained scenario of 1830.

2. Ten corporations and six privates, for up to 7 players
1870 has ten public companies (two more than 1830's eight) and six privates, with more room for parallel expansion without constantly clashing with rivals. It also supports up to 7 players, one more than 1830's maximum of 6.

3. Share price protection
A mechanic that doesn't exist in 1830: 1870 includes "price protection" rules that cushion a company's market value from dropping under certain circumstances, making stock management somewhat less harsh than in 1830.

4. Discounted reissue of treasury shares
When a company reissues its own treasury shares in 1870, it can do so at a discount of up to 25% off the current market price. In 1830, issuing new shares (when possible) is always done at market price, with no such built-in discount.

5. Destination bonuses for every corporation
1870 rewards companies that connect to their assigned destination city with a bonus unique to the game, a directed-expansion incentive that 1830 lacks (1830 has no destinations assigned to companies).

6. Privates with their own money-generating abilities
Beyond a fixed revenue stream as in 1830, some privates in 1870 (like the Southern Cattle Company or the Gulf Shipping Company) have special abilities to generate extra income for their owner under certain game circumstances, adding an extra layer of personal optimization on top of running companies.

7. Same stock market design lineage, with extra layers
Bill Dixon, 1870's sole designer, was also a co-designer of 1830 (together with Tresham and Lehmann) and of its stock market. 1870 inherits that same price grid but adds price protection, redemption and discounted reissue on top, making it one of the 18xx family's titles best known for the depth of its stock market game.

8. A much wider range of optional rules
1870 ships with an unusually large set of optional rules (Diesels variant, $400 finish, station marker wars, original tiles, reissue capped at $200, original market, and a full "Bill Dixon's original rules" bundle that combines several of these at once), a configuration flexibility that 1830 doesn't offer.
