"Sly Cooper: Thieves in Time – sometimes referred to in the series’ chronology as Sly 4 – was developed by Sanzaru Games for the PlayStation 3 and PS Vita. After taking on the task of remastering Sucker Punch Productions’ Sly Trilogy for HD re-release in 2010 as The Sly Collection, this is the first brand new entrant in the franchise by its new developer. The game features Cross-Save functionality, meaning you can save your game on either platform and continue it on the other.
It is also a part of the Cross-Buy promotion where purchasers of the PS3 version will receive a digital download of the handheld version for free. Whenever I hear about that sort of deal, I get suspicious of the quality of the game in question, and if you are too then this review should do well in letting you know whether Thieves in Time is truly a steal or a straight-up con."
After Sly Cooper Thieves in Time was released on PS3 in 2013, Sanzaru Games has not had the chance to revisit the raccoon and his gang.
Is it law that every Sly game from Sly 2 onwards end on a massive cliffhanger? I wouldn’t be as anxious for a Sly 5 if they just gave Sly 4 a succinct ending.
On another note we still have yet to hear anything about how that Sly Cooper television series is coming along.
Sly Cooper: Thieves in Time Lead Designer talks about his passion for the project, how they would love to return the world of Sly Cooper, and how the first episode of the DLC is completely written.
Incoming unpopular opinion!
I thought Thieves in Time was decent, but a bit of a letdown to be honest. Sly 3 ended perfectly, giving a conclusion of sorts for the main 3 characters while still leaving a little room for imagination, and had some of the best moments from the entire series, (The fight with General Tsao, anyone?) then Thieves in Time comes along with its lame villain, destroys Penelope's character, (I legitimately thought she was being brainwashed or something. Plus, why the boss fight in that crappy little mech suit when she's a master combatant and tech wiz?) and logic that makes no sense even in a cartoon world, such as Sly purposely being sent to prison so he can break out by... Throwing the one ton iron ball he's chained to to break through the wall? When he's never showed this type of strength before, and never displays a similar feat ever again? Plus I thought the levels were better designed in earlier games, and the cast of controllable characters in 3 was much more diverse and interesting. Sucker Punch were the true masters of this series.
VGChartz's Adam Cartwright: "The stealth genre is one that some would argue doesn’t even exist – many titles include stealth elements, but actually fit into one of a number of other genres like action, platformer, or third-person shooter. Ever since the breakout success of the Metal Gear franchise (in particular Metal Gear Solid), though, the genre seems on much more stable footing and it demonstrated that you can have a veritable blockbuster on your hands relying only on stealth mechanics as the main gameplay element.
In recent years we’ve seen other things like Assassin’s Creed, Hitman and Splinter Cell continue to push the genre forward, although it still has somewhat limited appeal. Thankfully, the Vita has a healthy selection of stealth games available (and even more with backwards-compatibility), meaning if you’re looking to do some sneaking on the go then you’ll be well served with the console."
I always thought the Sly Cooper franchise was solid. 7 is a little lower than I would hope for, but that's still a solid score.
