@@AesxpizCrash 3 is the easiest of the trilogy ( although they did add a DLC ) to Platinum and was designed for the time trials but Crash 4 is way too hard, you have to play all the levels twice, once normally and then again inverted with a filter over it and you also have to do every level without dying as well, both the regular and inverted versions have gems so you need to pick them both up, do the time trials, coloured gems ( the blue gem being the most frustrating to get because you have to negotiate this very tricky oriental themed level with the tornado mask without hitting the boxes, the saving grace is that you can use the bonus round platform as a checkpoint). So I hit a brick wall with Toys for Bobs Dark Souls Crash and it sits at 75% and thankfully I didn’t buy it, it was free on Plus. It took me 1 month to Platinum Crash 2 and I never played the PS1 version, but apart from the Piston it Away level it’s easy compared to 4, even Crash 1 is easy compared to 4. TFB did great with Spyro, although he was always easier than Crash anyway, but they can do one with regards to the Platinum for Crash 4.
You're doing the 3rd and 4th game? Warped is the easiest out of all of them, so it shouldnt be such a hassle. Crash 4 on the other hand.... was not worth completing it 106%...
