Yeah, it's a shame. I was trying to roll a good Lakes map the other day, as it's pretty much a GP map that wraps, but it can feature jungles and small seas. Finding enough spots to settle is often a problem though, as on Great Plains you can usually back-settle the mountain/hill area west of your spawn at least, but Lakes wraps so there's more competition for city spots. Still, my fastest Prince SV was on Lakes, as were my best Deity DomV and Sacred Sites CV. I'm quite certain the map has a ton of potential, for both peaceful and warlike <T190 SV.A downside of GP maps are the lack of jungle, which ideally would be in the 3rd ring (or a bit in the 2nd ring) of your city.
