Actually, and I know I'll be lapidated for what I'm about to say, all in games are quite easier than other combos. Having everything in induces the following effects:
- higher chances of playing "speed Arkham": every turn a new gate opens, but the game is about gates being sealed and nothing else, and if you're good at the game, you're able to have a different investigator almost every round with five clues to dive into a gate. Atlach games become noobish, and generally everyhitng's smoother
- lower odds of having monster surges, so that the board is rarely clogged with monsters blocking you the way to a gate and triggering terror and other obnoxious effects
- the board reduction factor has such a great impact on the game (plus with IH and DH boards in play you have also a +1 to the gate limit) that you can play 6 as playing 4, and this means it's enough each of your characters seal ONE gate in the whole game that you win for sure; if you play 4, then it's like you're playing 2 with an augmented gate limit
- higher number of unstable locations implies lower odds of gate bursts
On the other hand, playing one exp board (or two if the second one is Kingsport) plus MH is a *nightmare*: the board reduction factor has a lower impact on the game, bursts and surges are more likely to happen, hence you risk losing some turns more to control / clean the board and you raise the odds of drawing nasty Mythos (double doomers and so on)
If I look back at my stats, I think I've lost only one game with all in out of 44 (Scenario 2 of Avi's League, and I lost it beacuase of Avi's special rules, not because of "all in" - for those who are not familiar with the Scenario, it's a Glaaki one where, immediately after the setup, you have three Servants entering play), while my win-loss ratio for 2 exp boards in is somehow lower (92% more or less) and generally (even if victories are still scored consistently) are more "strategically challenging"
