Alright. After almost 4 yrs in-game time, half a year real time, ~20 patches and ~6000 dead enemies I am finally finished.
And I have to say that, even in this pre v1.0 state it is the best mod i have ever played, actually better than the original game, which was already one of the best computer games. Thanks a lot to everybody who contributed!
I particularly liked:
1) The background story. The bootypedia entries contain a surprisingly large amount of wittiness, while still creating a serious enough universe (taking the original game as a basis). Despite the many scifi references it is amazing how it avoids common videogame cliches and stereotypes. When I first heard about the "all female band of mutant pirates" I was expecting some nerdy pixel-boobies fantasy. While it might still be exactly that, it is very different from all the others around. Very refreshing.
2) Things make sense. When I assaulted my first frighter i was excited to see bunk beds for the crew and a toilet. Seems trivial, but many games dont care about these things much, considering impressive visuals and artistic considerations more important. But IMHO in many cases the atmosphere profits more from a realistic and believable environment.
3) Balancing. Over the years I was using a lot of the available equipment and a lot of it turned out to be useful at least in certain situations. That was of course the big weak point of the original XCOM, where the AVENGER was not only the best craft overall, but the best in every single respect. There was hardly an reason to mix equipment, because there was always a clear best and the rest was just worse.
So in conclusion XPiratez takes a very good game and eliminates the biggest flaws, i.e. balancing and the somewhat weird premise that earth fights the Alien invasion with 2 Interceptors and ~10 soldiers that seem to hardly have any combat skills.
I hardly have suggestions for improvement, and most of what I noticed was stuff that will in all probability be included in a v1.0 (or was in fact already included in a patch, which I just missed). Most notably:
1) The maps for enemy hideouts. It doesnt make sense that they look like alien bases. Similarly for the frigate, which uses the old supply ship from XCOM. Also at some point I noticed that the lighting got improved (bright engine in one of the cutter maps), but most maps dont use that possibility. I think in a lot of cases the inside of the ships should be brighter in general.
2) At one point the game start was completely changed (I restarted my campaign at this point). While this made sense from a gameplay perspective (you now get to use much more of the low level equipment), it still felt strange. Why do you already get protection money when you just escaped the asylum? How did you get the first brainer to join? Also (when I was playing that part) you hardly got any mission, because you cant shoot anything down and civilian crafts never landed. Again, this might already have been improved.
3) On balancing: The Annihilator armor is very strong. One might consider it as a gift to the player for holding out so long, that armors never need to be changed again. But it is unfortunate that it very quickly makes the three armors below it (Brute, Harbinger, Assault) superfluous. Other things that seemed strong to me were the Bio Suit and the Flechette Multicannon (one autoshot at short/intermediate range can kill every single unit in the game). On the other hand all flamthrowers seem weak to me. Also voodoo:excess is imho much weaker than the others (communion the best).
Again, thanks for all the work.
