domain Renew or drop? Playzie.com and Thinkcentive.com

[kaposzta]

Two of my brandable domains will expire in a few days:

Playzie.com
Thinkcentive.com

I've submitted these to Brandpa but these were rejected.
The reasons why I might not renew them:
- while play is a nice keyword, -zie suffix is not that great,
- Thinkcentive is pronounced similar to incentive, but why would anyone (e.g. a company) incentivize thinking?

What do you think about these names?
Thank you in advance!

I want to like this one, but yeah it doesnt feel strong. Also noticed that before you reg'd it last year, it was dead for 9 years. Showing that its not a great word.
