You are missing something. Is this router2? It does not know how to get to 192.168.1.0.

I generally like to debug routing problems with a sniffer. Install tcpdump(-mini) and check where each ping stops.
Also, send the "route -n" output for every device.

Hi,

router1 needs to know 192.168.2.0/24 is via 192.168.3.2

router2 needs to know 192.168.1.0/24 is via 192.168.3.1

if the routers 1 and 2 are default gateways you do not need to put a
route on the PCs, but the routers must have them.

you cannot ping in current configuration because router2 does not know
how to get to the 192.168.0.1/24 network, so the reply never reaches you.

Put routes on the routers and I think you'll be ok.
