One thinks rather mischievously, what if this is combined with the 5.1 patch - and hence you can optimise economy from the get go, because WC is trivial hence economy is nominally the same, so qoou's records might be assailable (Now it is merely a matter of choosing the country with the right modifiers and the best position to attempt this). Of course this is as has been pointed out not entirely the most legitimate means of playing the game, however there are two things that point me towards saying that it should be allowed;
1). EU3 is coming to the end of its lifespan in any case, and I think all these glitches should be recorded as they were included as part of the game engine regardless of our intents, in the same manner to turbo-annexation in IN which was probably on a similar scope to this. So as its a part of the game it should be recorded as a 'record'.
2). You can make the argument that it is broken, however the majority of the tricks that have presented themselves in this thread are of that very nature just depending on severity, I mean the old record of WC was held by someone who simply turbo-annexed with France. Forming Ireland as England etc., they are all in essentially highly gamey from a historical perspective and not in any way with the spirit of what the game is supposed to nominally represent so to claim it as cheating I think is a bit silly. Yes it invalidates alot of previous thought, nonetheless it is part of the game whether it is liked or not considering most of the things that were done in this thread were 'glitches' whether by design or not. Does somehow increasing the %TE of the world to several thousand sound non-glitchy? That was the point of this thread, and the innovative ways to break the game, so in my opinion it should stay.
Of course does this 'glitch' work on previous versions of the game too, because it would be interesting to see whether it is indeed possible to do this in say 1.0-4.1 and combine it with other exploits (of course that is probably something to be frowned upon because I guess it is picking a version so that you can get 'optimum' play from that of the player, but then again records are allowed from previous versions with different mechanics and RNG's). So either way its a little moot, but from my perspective I would think it should remain.
