Tacitus's board-to-board with Halopediaman

Question on the walkthrough infobox templates, do we prefer an image under the 'era' section that links to the associated game (as seen in the walkthroughs for Halo Reach and Halo 5) or just a standard [[]] link to the associated game (as seen in the walkthroughs for Halo CE and Halo 3)? A third alternative is found on Halo 3 ODST articles where the actual era image thumbnail is used straight up with no link at all.

An additional question: Do you think it'd be worthwhile to create a List of Walkthroughs template to put at the bottom of walkthrough pages similar to the soundtrack one from that earlier project (with subgroups for each game's walkthroughs)?

Thank you.
