Over G Fighters's missions are pretty straightforward. Protect this group, invade enemy territory and destroy all the opposing fighters, do recon, etc. If you've played any other flight combat game, then you know what to expect out of this one.
Where Over G doesn't appeal to my personal tastes is that the game is a little less arcade-like than I would have liked. There were several times when I just wanted to jump into a dog fight, take down some enemies and leave the game. Instead, the game's two modes, Scenario and Challenge, either require a lot of setup, take a lot of time to finish or both.
Scenario Mode takes you across the world going from country to country taking out targets, while protecting your wingmen and other allies. The steps to get into a mission involve not only listening to briefings from the aforementioned generals and politicians, but also selecting your craft and selecting the various guns and missiles that your plane will launch with.
Challenge Mode has two categories, Arena and Strike. Arena Mode is essentially a survival mode where you and your friends take out as many enemies as you can before you either crash or get taken out. Strike Mode lets you design the scenario on your own and select everything from your aircraft, weapons, wingmen, types of enemies and their altitudes and positions. Again, not really something you can just jump into.
In the end, Over G Fighters feels a lot more like a blend between a flight sim and a flight combat game. There were too many technical aspects to the actual flight aspect to make it more than just a combat game and the missions were more than what you would find in a sim game.
