My rating is 8/10, but i really loved Disharmony for it's Challenging difficulty though. Additionaly i think ES:Disharmony has better space battles rather than ES2 (Fighter-tracking Camera, etc.)

What is your opinion? 

Old post, but so's everything in the ES1 section...

It has a much smaller filesize and isn't as graphically intensive. I haven't been able to play ES2 too much and I don't even own it right now, but I like ES1 a lot.

I'm not sure how to feel about it becoming free. It's obvious that it was successful, but ES1 still has lots of value, and rereleasing a game for free tends to strip it of any value. (I'm not talking about freemium games, as those aren't really free.)

It seems some think the first is a better game, and they aren't always nice about it. I don't know enough about ES2 to go that far, but I doubt it's that simple.
