I don't understand some of the posited reviews saying that this game is too hard or chaotic or bland.
The game is not too difficult, it just has a bit of a learning curve. Truly, I thought it was too easy at first. If you're a passable shot in Wing Commander or Ace Combat or anything like that, you should be a dead-eye marksman in this. I went through the first three levels not using the lock-on function. It was only later that I discovered the game has a freaking target-lead reticle. If you cant shoot using that, don't say anything about it because you're a walking advocate for gun control.
Of course, then comes the part where you get a mech. Maybe that part was easier for others. I had no idea how to use the damn thing at first. I'll tell you this much; it's not a fighter, but once you get the hang of it and get some strike mode upgrades it's hell on...legs. The Strike Suit is unbelievably maneuverable, not the slow thing some would have you believe. I became an ace with it fairly quickly just by spamming random momvement input and keeping the cursor on-track. Anybody can do that.
As for chatoic; yeah, it's chatoic. Gloriously chaotic. Ever play "Homeworld" and wonder what it would be like to be an interceptor pilot in one of those mad dogfights where everyone is set to evasive tactics? That is this, glowing contrails and all. Even so, it is not unmanageable. The "F" key will helpfully direct you to what you're supposed to be shooting at. Just use it and use it fast because you will need time to orient yourself to which side of the a capital ship or somesuch your target is actually on. An improvement to this game would be to make targets with no LOS a different shade of red.
Then there's blandness, an argument I have seen in every video review. There aren't enough varieties of enemy ships or varieties in missions. I can sorta see that; everything boils down to attacking or defending, rather than including the more diverse missions of space fighters, like attending airshows or flying to Cancun for a weekend.
I jest, for there is some merit to the argument. Why doesn't the mech do more mech things, for instance. Well, for starters this began as a freeware game and doesn't have the engine for that sort of thing. For another, it's a Japanese mech so it doesn't have to make sense. It's all about awesome battles set to goregous backdrops and great music. Call me crazy, but getting those out of the way is a major step to making a decent game, so I don't regret a cent of the cost for the steam mega bundle.
That said, one of the really nice surprises in this game is not just the chaos, but the frenetic pace of the action. Hands up if you've played an "intense" game where something needs to be done "right now" and it turns out that you've got forever and a couple of sick days to do it. Not so in SS0, thank the powers that be. When told to ignore the enemy fighters and flak, it's no joke most of the time. You really do have to be quick, especially if you want the juicy upgrades.
It's not a game for everyone. If you don't like explosive arcade flight sims, you won't like this game. If you think the Strigoi Squadron in Ace Combat was too easy, you need to spend a few hours in a centrifuge to learn some respect for gravity due to acceleration, but if you're somewhere in-between I think you'll like this game.
