Been playing SFC3 regularly and am for the most part rather immpressed. Despite some pretty deep changes in gameplay the 'feel' of the game stayed surprisingly close to that of the first two installments. And now for the things I personally wish were there but are missing in the current configuration. *Sigh* Ahh well, there's always hope for an Expansion.
1) Defiant's third primary hardpoint.
The canon Defiant clearly displays on numerous occasions (The straifing run on the Negh'var in one of the DS9 alternate-universe episodes being a prime example.) That it has a standard omni-directional phaser mounted in the middle of that circular portion atop the hull which is presumably the warp-core. The fixed-foreward mount located farther foreward on the refit screen seems to incorrectly assume that the onetime picturing of a powerfull phaser-cannon firing from there (Forget the episode name, Defiant get's most of it's weapons hosed and is chased into a Gas Giant's atmosphere by two Jem-Ha'dar attack ships.) which is in fact an improvised weapon using the main deflector as a one-shot phaser emitter as opposed to being a fixed weapon system. Also the original Defiant appears to have provision for three torpedo tubes instead of the four hardpoints seen in the UI but then again that third one could have just been strictly for launching probes.
2) Federation Destroyer.
I personally would've preferred to have seen the Steamrunner in that slot as opposed to the Norway, but maybe that's just me. The Steamrunner seems to have a more aggressive asthetic than the Norway which would've made it perfect for a mostly combat-oriented starship game.
3) Lakota Excelsior.
One episode of Deep Space 9 involving conspiracies pitting Sisko and co against certain factions in Stafleet features a special refit of the Excelsior class widely known as the 'Lakota Refit', after the first ship of that class to have that refit. The refited Excelsior featured a larger number of heavier phaser arrays and had it's photon torpedo armament exchanged for Quantum torps. One of the new phasers had a Very broad fire-ark, seen shooting UP at the Defiant from the dorsal hump the nacelle struts are fixed to. I WANT this ship! Wether it's by beefing-up the Excelsior so it can be refitted to this configuration or by making a more powerfull (and expensive) class of hull with the Excelsior model, I don't care which.
4) New races/weapons.
Dominon and Cardassian. And some of the new Voyager weapons. Maybe not UBER tech like the Transphasic torps or the Batmobile armor, but I'd love to see something like the Isokinetic cannon be made available to Feddie ships.
5) Prometheus.
I understand some modders are working on this already, so I'll just wait for that.
That's all I can think of right now. Take care now, bye-bye then.
