Good, good. So there is no need for delay. You're aware of the likes of restriction based, challenge runs, yes? Action games tend to have a certain array of them. GoW is no exception. For instance, the start run called a "No Upgrade Run" (NUR). I should very much like to see you find greater replayability in learning the combat system to a greater extent and rising to the challenge of becoming a series vet as such.
Would you prefer starting with GoW1? A NUR or NUR+? The latter is a NUR combined with NER (No Extension Run). Basically, the latter means you won't be using EXP for upgrades or collectibles (or other means) to extend your various bars (MP, HP, etc.). In such conditions, you will learn to master the basics.
For instance, collisions (usually referring to foes colliding with one another more often than with obstacles *GoWIII*). How do you imagine they work in this game? It is an important detail (particularly for GoW1 and GoWII). Less so for GoWIII (works a bit different). GoS nerfed them and simplified it to a stupid degree. CoO doesn't have them at all.
Rage is simple enough in GoW1, but it changes in a rather sizable way for GoWII.
If you've need of some tidbits on enemy HP, percentiles, damage values, etc., I can be of service. Same for tactics and exploits/glitches.
~I presume you didn't have too much trouble with VH, but odds are you didn't get too much out of it though you managed to clear the setting. It takes many playthroughs with focus on different aspects (often in special conditions) to get a good and thorough grasp of things. Whenever you're ready. Should you have the means to record, that would be ideal, but if not, I can provide run skeletons to fill (for evaluation, questions/comments, etc.).
