There is almost no problem in playing both TGM and TAP, even in the same half day, we can still perform a new record in one of these games in mixing the session. But trying to play both TI and TAP is another story. I remember the first time, after my first heboris ti period of 4 months, I decided to come back on TAP in thinking that I would destroy the game thank to the speed improvement provided by DOOM, and I lived a disaster during 3 weeks at least to recover. My friend Bou lived this event with me and he did not understand as well why DEATH 300 looked so slow for him after DOOM but still impossible. Today I need less than 3 days, and I am sure that 3 days only makes me recover 90% of my level, and the last 10% of accuracy comes only after many weeks. I am wondering today if I can still work on 2 opposited versions : SHIRASE and TGM1. I think that the two games are so far regarding the speed and the scenario that they won't parasite each other. And I wish to hear some opinions about this problematic of switching.
