It's pretty easy to admit we're no longer in the age of a manifest destiny mindset. For the battle hungry colonizer in you this has to be depressing information... but don't fret! While it's not land based warfare, Colonial Wars provides you with a great opportunity to flex your naval military muscles. This real-time strategy game starts with you as a red colored island looking to expand your colony. To send your little soldiers off to battle, click and hold on your island, then drag towards the island you want to invade and release, or drag to another island under your control first to send multiple armies to the same destination. Doing so sends over half the number of troops displayed at your island, and you need to send over a larger number than the one displayed on the enemy's forces... which is exactly what they'll also be trying to do. Luckily, the islands regenerate fighters and there are upgrades available that will help you out and hinder your foes.
Off the bat the game might seem too simple for the seasoned strategy gamer but the difficulty picks up as you plow through the levels. Part of the difficulty comes not only from island positions on the map but also from more than one enemy to contend with. Upgrades provide a helping hand though the price for them becomes quite steep when compared to the rate of obtaining the gold. While the boats and planes will seem rather sluggish the speed boost comes in handy to cast away that frustration. You won't need to be a master tactician to beat the game but you will have to keep your wits about you and that's what makes this game all the better. It's a familiar concept, but it's fun, well presented, and fits perfectly into your day.
