The following opinions are based on hundreds of hours played, all versions of the game, modded and unmodded, online and single player.
When I first bought it, I was very excited about this game. And in a sense I still am. The "awesome" factor is definitely the iron engine. Impressive to say the least. Ironclad succeeded where much bigger names have failed miserably.
Unfortunately that's about the only awesome factor as I feel the developers have failed to capitalize on an engine that promises so much. Let's start: with the lack of campaign: I'm sorry, but this is not another online shootter, this is a strategy game... they do go together, strategy and campaign, that is. And if your hillariously embarassing excuse that "we offered extensive mod tools for players to create their own content" were indeed true, then I must ask: why the story telling in the intro of the game? It felt way out of place.
Almost all games nowadays are easily modable, and that is more or less something the devs cannot avoid as most extensive software projects (which most games are) are "modular". They need to be so in order to support many coders, artists etc. working together. Being easily modable is at most a bonus not something that can be exchanged for content. After all I don't spend my money buying your game so I can spend hours upon hours creating content for myself or worse, downloading and crash testing content from other people. I'm sorry, but I don't want to buy a game engine. I want to buy games to have fun, not to get a second job creating "user content"; or wait for your numerous patch fixes and "content patches", content that should have been there in the first place.
I am not even going to mention the lack of mod tools, unexcusable for a game that presumably truncates content for flexibility. You want to know how mod tools look like? Check out TES construction set for Oblivion or Morrowind. It took the devs 3 patches to fix needing to transfer over 1gig of meshes and textures to the mods folder in order to mod game textures. Lol. Not very adroit, my dear devs. Should I mention AI modding? Hurrrm
Also, claiming that multiplayer was factored into the initial release package is ridiculous at best, as the first month the online play was riddled with bugs and exploits, not to mention balance problems, all easily avoidable through testing (these were issues players picked up in the first week of play). Learn to beta test or demo if needed. Don't release the demo months after the game release... that's ridiculous. Demo stands for demonstration. Bah.
The diplomacy. It's ridiculous at best. I don't know whether dimplomacy was implemented in such a simplistic way because of game engine constraints, but either way it sucks atm. There is a short period (40-50) mins at the start of the game when you run the risk of all AI players ganging up on you. That is until you manage to establish some cease fire treaties. After you managed to build your alliances the game is won. You can take one or two players out at a time, untill all of them are gone. There's nothing dynamic, no backstabing (since if you have the correct approval percentage the AI player will never break already existing alliances), no forced or bought alliances out of necessity, no temporary ceasefires, no tricks, no research trade, no ship trade, no tributes etc. Also, unrelated to diplomacy, there is no espionage.
This trully renders the game stale. Why bother having hundreds of planets and 6+ stars with up to 10 players if all you do is blitz research followed by automatic spamming of favorite frigate/cruiser/battleship and a seemingly unending process of nuking and then colonizing planet after planet until you reach the home planet where you, at last, get to fight one big battle. There are few strategies as for example there is no serious way one could outtech another's fleet and thus fight numbers with quality.
On top of that the AI sucks bad. So tired of fleets of percherons and robotic cruisers. With such a simple game... I can't help but wonder why?
Anyways, going to go read a book or watch some TV. Will give this game a few months for the devs to get some sense and crank out the content that was supposed to come with the original game. I feel like I was given a lollypop stick without the lollypop.
