That's a sentence I really needed to hear, although it makes me green with envy. I do hope you can still say the same a month from now, buuuuut considering you've played this game once already, put what, 50-75 hours into the preview build alone, and still think it's amazing? Well, we might have a Saints Row 2 repeat on our hands, I hope. I'll be eagerly awaiting the review, at least that'll come out before my copy does, haha.
Honestly speaking, I thought Saints Row 1 was "meh". Not a bad game, but it was a typical GTA clone. That was its purpose, though. They released Saints Row between the GTA:SA and GTA 4. The thing is, they released Saints Row 2 right after GTA 4, which sucked a lot of the oxygen for Saints Row 2. Saints Row 2 is the superior game when you compare it to Saints Row, but the momentum from GTA4's release stalled the momentum of Saints Row 2. A lot of success for Saints Row was because people were itching for something similar to GTA. It's why they chose to release Saints Row 4 before GTA5. Although they deny it, it is smart move to release it before GTA5, because it would mitigate most of the damage from GTA5's release.
I digress a little bit, but my point is, because they do not have to worry about working with a new engine, and with less publisher interference, they have time to work on the content. Also, because few people complained about the fundamentals (core gameplay mechanics), they only need to do a little bit of reworking there (they added super powers, a part of the new fundamentals), which also allows them to focus on the content. At this point, I think I got a good read on how good SR4 is, even if I don't have the game yet. There's at least enough info out there to tell us about at least 4 to 6 missions of info.
My concern right now would be SR5. It's almost certain to be on the next-gen consoles. Problem is, are they going to use a whole new engine again? Because if they have to do so, I'm going to expect this pattern to repeat itself.
SR1 = Meh, SR2 = Great, SR3 = Meh, SR4 = Good/Great (?, Informed Speculation), SR5 = ???
