Like I personally could not get passed the first level in GTA IV. I found it soooo boring. I've never been a GTA fan and I tried GTA IV at a friends house to see if this GTA was any better but damn no different. That's why I felt skeptical at first about Red Dead Redemption but when I got to play RDR, it was an immediate hit for me and that is why I'm looking forward to Agent. And right now RDR sits on a 95 when I find it far better than GTA IV. I just find it hard to believe that still today that GTA IV is yet to be beaten on Metacritic. I find it sad that great innovative IP games like Bioshock, Uncharted 2 and Mass Effect 2 all sit 2 whole points below GTA IV...
The same happened to me. I could not believe the game was so over rated.
But just like you before your purchase, I feel compelled to buy Red Dead Redemption. I'll do it anyday soon.
