I played Anacreon a few times and it looked cool... just the interface was so confusing, I seem to recall having to memorize arcane commands like G to build fighters and Control-O to use a warp gate
What I did like about that game, though, was all the "stellar constructions" you could do - you know those stargates you could build in MOO1 and Stars? Well instead of just building them at one of your systems, you could (in fact you HAD to, IIRC) build them OUTSIDE a system, where you had to actually defend them with ships and such else someone else take them over! You could even build artificial colonies or factories in the dead of space, similar to SE4's stellar manipulation only you don't need asteroids!
