Happy-Healthy New Year to you too, Tally Ho!
I think that the Mystery of the Ancient Series as well as the League of Light series (Mariaglorum is the developer) are all quite good.
They don't really need to be played in any particular order, as I recall - although with the League of Light series, there is an ongoing story in some of the games about a little scarecrow, so from that standpoint you may want to play them in order (I personally liked the little scarecrow and did not find this to be quite as hokey as it sounds).
Also, while the first Mystery of the Ancients: Lockwood Manor CE, is a good game, it came out in 2011 and has no voiceovers as well as more hidden object scenes - just letting you know in case this would make it a less enjoyable game for you.
I would start with the following as being some of the best:
League of Light: Dark Omens CE
Mystery of the Ancients: Curse of the Black Water CE
Mystery of the Ancients: No Escape CE
League of Light: Wicked Harvest CE
The others in both series are all above average - the above are just some of my top picks. Here is the order in which they were released:
Mystery of the Ancients series orderLeague of Light series orderOf note, League of Light: Growing Threat CE is more of a straight HOG than a HOPA. The rest are all HOPAs.
This thread has gotten very long, so I am going to go ahead and lock it. The discussion can be continued in the new thread that I have created
