I bought this game for my collection during the UBIsoft sale, just because I remember playing it as a kid. So I decided to refresh my memory.
Why aren't there people who make games like this anymore? Rainbow Six is as fun as it used to be years ago and plays so much differently from all this casual action games of modern times. Its old, but not in the bad meaning of old, it is classic, oldschool if you please :D. There is a lot of replayability as well: you can follow premade plan, just rush it as lone wolf or with the team, make up your own strategy for the map and even spectate everything while your team just follows orders.
But who am I telling it to, I doubt that anyone who never heard about these series before will ever read this review of my. If you are considering buying: don't hesitate. Rainbow Six 3 is truly the Gold of game industry.
And best part is that it supports modern resolutions just fine (well except of tiny little main menu, but whatever.)
