Commodoor - Series 2 and 4

[Red2048]

While browsing the Commodoor pages I noticed that in;

Series 2:
It has 3 indentical games that are different from all the others in the serie.
They are the ones with a shell colored in red, the front metal plate is flat, and have another rearside from all the other games in the Series 2.
I think these belong to a separated serie, unless they are kept there for a reason.
- Cat and Mice ( gameID 3558 )
- King of Comos ( gameID 3508 )
- Shogun ( gameID 3541 )

Series 4:
All 4 games, looks like these are games for the Serie 2.
Are these splitted for a specific reason?

You are right about those 3 games in series 2. Will split them off to separate series.

Series 4 has 4 buttons in stead of 2. That is why I separated them from series 2.

Ah ok, I wasn't sure, in that case then the following game has 4 buttons in series 2, this should be in Series 4, correct?
- Panda ( gameID 2152 )

PS: Is it ok that I add the gameID like this?

[paccy]

You are absolutely right. Panda I moved there. Thanks!
I can find the games by ID but manufacturer/series/name is easier.
