I sympathize with your indignation, but for the purpose of this poll I wanted only the most popular, vast and archetypical (for better or for worse) series. The Cotton series produced three-and-a-half horizontal entries (Cotton 100% is moreso a reimagination of the first game than a full-fledged original game, similar to Super R-Type in that regard) and is not nearly as well-known or emblematic as the above titles. That's no implicit statement on the quality of the Cotton games, it's just not quite fitting for the theme I was going for here - I also love quite a few other horizontal series which I omitted for this poll (Parodius, Rayxanber, the inofficial "Capcom flying man" trilogy...), I hope you (grudgingly) understand.
Anyway, as for my personal vote:
- I enjoy Darius games quite a bit, although I haven't played G-Darius or any Darius Burst after the first PSP entry yet. Solidly crafted games with a lean, elegant flow. I particularly like II and Force for their stronger focus on level design, notably Force has some unusually strong design choices in that department. I don't understand how any of the games could ever include a random element of scoring, it's a glaring problem in the first game and still problematic in later games where it is featured. There are also some structural weaknesses in the aforementioned level conception when they just repeat three or four enemy formations in a row without much of a substantial change in terrain or positioning. Not too fond of Gaiden, Twin is fairly average in every regard.
- Love the Gradius series. If I were to vote "objectively" I would probably have to go with R-Type, but the higher degree of improvisation and looping gives Gradius the edge for me. Those are the only games out of the poll where I feel compelled to revisit them over and over and over again, trying to clear yet another loop or two or three and getting a better score. I'm also astounded how much small decisions completely alter the experience: do you pick up a fourth option in II or Gaiden? If so, only at a specific spot or right away? Do you use the fourth option for a stage or two and then let the option hunter take it away? The amount of speed-ups is crucial for enabling certain strategies and techniques with the options, three speed-ups allow a lot more tricks than two, and a fourth speed-up facilitates complete screen control at the risk of crashing into terrain. I also think that the "Gradius syndrome" is more of an exception than a rule, most checkpoints in most games are surmountable with enough practice - I even looked a tiny bit into III's (AC) first loop checkpoints, I overestimated some of them, too. That's not too say every checkpoint is balanced (they're most certainly not), yet I don't believe it's as bad as some people make it out to be. I also adore the audiovisual presentation of most games.
- R-Type is a close second for me. I, II and Delta are all close to perfection for me, and III is still excellent. Not too enthusiastic about Leo (which doesn't play a lot like an R-Type game) and Final has some blatant problems even though it's not terrible, either. It's baffling just how balanced the first game is, you can use every weapon for every stage for some useful effect, it boggles the mind. II is certainly more restricted since the DNA laser is the better choice under most circumstances, but I dare say the puzzles are even more engaging. I've not seen anything as thrilling and pumping as the final stage in the second loop, that is true horror, indeed. Encapsulates everything that is great about memorizers. My only small gripe is that due to their hermetic nature it's a bit cumbersome to get back to them for better scoring. While I love multi-loop marathons I'm not keen on checkpoint-milking; I'd admit in an instant that it requires a lot of knowledge and skill to proficiently milk the two arcade games in an efficient manner, I don't want to, however. Delta is the only game I would want to revisit since the simple scoring system is also satisfying to pull off, and you only have to sacrifice two lives.
- Haven't played the first, fifth and sixth Thunder Force (or TF AC), so I'm not as familiar with this series. Hate II, indifferent towards III/Spirits, adore IV. That's not nearly enough for me to consider voting for it.
