Current Ingress player, posted the IITC map above.
In some ways PoGo has more gameplay than Ingress. In some ways, less. Right now, the only PvP happens at gyms. However, you can actually do shit between porta^Wpokéstops, even if it is just "catch pokémon" and "evolve shit".
In Ingress, PvP can be small scale, or it can involve legitimately fucking shit up for entire counties, states, even nations and whole continents at once by burying them under megafields. Getting in the way of fielder plans by throwing spam links up in the way. Sitting on a portal and just dropping resonators on it all casual as fuck while some guy wastes his entire ammo supply trying to take it.
You also have to move about a bit more in Ingress. Portals can only be hacked four times without modification, then they burn out for something like 4 hours.
Speaking of mods, Ingress has a lot more of them than PoGo's Lure. The Multi Hack portal mod extends the number of times you can hack a portal by some number, but at least +4 hacks. Shields buff a portal up so it's harder to take down. Turrets and Force Amps are your nasty mods that make portals go from just hitting attackers back to bitch slapping them down to 0 energy in short order.
Everything asides shields has a stacking penalty (so two force amps isn't 2x better than one force amp). Mods come in common, rare, very rare and special varieties with different power levels.
There's strategy in fielding, with ways and means of layering fields on top of each other to maximise the amount of MUs (Mind Units) you're getting per square metre. Or maybe you want to link a portal farm up so that each portal gets the maximum amount of defensive boost from linking, which is a different strategy.
However at the end of the day, you're basically drawing lines on a map and trying to make triangles. Probably more capacity for ebin troling though, since everyone playing the game could see your nation-sized green and blue dickbutt on the map.
