They're both great games but they're also very different from each other.

I'm relating it in the time period it's released in, and right now inFamous is the prime example of that recently. That and a lot of other game design traits similar to inFamous.
The blast shards don't improve your abilities in Infamous, that's XP. The blast shards just increase your maximum energy.
And by your logic, Infamous is just a Crackdown rip-off.
