To clarify, it is okay to post on a thread that has not been posted in for 20 days if the topic is still relevant (Such as a Game or Forum Discussion where the topic being discussed is still an existing issue/subject in the game/forum today). Concerning the Forum Games, we ask in the Board Guidelines that you do not post duplicates of games that already exist, and encourage you to continue off the already existing game. Therefore, it is perfectly acceptable to revive an old Forum Game that you wish to continue.
Generally, as a rule of thumb, we ask that you do not necro threads that are more than a year old; however an exception to this rule would be as a mentioned above. This rule is generally in place for threads such a Game Help threads, Creation threads, etc. where the original author may no longer be active or the topic is no longer relevant, therefore there is no reason to bump or post in the thread. Hope this helps.
