I just wish that the fore runner to Disrupters, the Particle Beam Cannon, could be included into the stock weapons of the game. If only they'd done the direct fire weapons in a weapons list file so that tables could be added as with a Star Fleet Battles SSD. I would have added these in for an alternative point defence.
Yes, earlier battles are a bit more difficult. Loosing any power box, especially a Warp box, seriously affects a ship, more so than with TOS period ships. There are no minor damage hits that can be shrugged off....
Performing a long range scan either stops a ship dead or reduces speed to a dead crawl.
In LAN games players tend to only power up the weapons that they intend to use for a particular stage in a battle dependant on fighting stretegy.
Shields are usually only powered up when intending to move into range of an enemy. Even with incoming missile salvoes, speed, dropping bombs and firing one's own missiles as anti-missiles is a better option. Power is better utilised for weapons charging, damage control and movement.
Overloads of Disrupters or specific Disrupters is not always possible. Players have to choose more between a high attack speed or overloaded Disrupters and a slow attack run. As the direct fire weapons tend to be short ranged, moving out of range isn't such a problem. Missile salvoes tend to force an enemy to keep a high speed thus limiting the power available to them for weapons charging.
The AI tends to play earlier ships slightly different, perhaps reflecting on the power availability.
Its a more skillful game....
