Currently we have lost some structures from the old game, gained one and appear to have potentially redundant ones
Redundant - Jump Gate and Beacon.
Previously you had to research these and so availability was delayed. Now they are available early on and quite cheap.
Suggestion - merge then to create Jump Beacon and put it behind Metropolis. Reduces travel to one end to 25% for you and allies, at both ends it reduces travel to 50% for you and allies.
Addition - Boosters.
Bring these back in and put them into the research queue, maybe after strips or just before
Cap total planet abundances at 150% so in Gal 1 won’t really be worth it most of the time due to space usage but would help close the gap in the outer gals a little.
Not sure how to add energy booster into research, maybe just make it available after Metropolis or create energy research which would create something else to spread research points over.
