"In the end, Colin McRae Rally 2005 upholds the fine tradition the series has established. A solid driving model is bolstered by a good career mode and online racing that provides a glimpse at where the franchise may be heading in the future. For those new to the series, Colin McRae 2005 offers a lot to keep you busy, and it's certainly worth its relatively low price. Those who already own Colin McRae Rally 4, however, may find 2005's online mode too sparse to justify a new purchase."
